  • 2. 

    The rate at which an object moves is __________.

    Explanation
    The correct answer is "speed". The question is asking for the term that describes the rate at which an object moves. "Speed" is the appropriate term to describe this concept, and it can be written in different cases (lowercase or uppercase) without affecting its meaning.

    Rate this question:

  • 3. 

    A(n) __________ force is when forces are moving in different directions.

    Explanation
    A balanced force is when forces are moving in different directions. It means that the forces are equal in magnitude and opposite in direction, resulting in no net force on the object. This causes the object to remain at rest or continue moving at a constant velocity.

    Rate this question:

  • 4. 

    When you describe motion, you are comparing it with some frame of reference.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    When describing motion, it is necessary to compare it with a frame of reference. This is because motion is relative and can only be understood in relation to something else. A frame of reference is a point or system used to measure and describe the position, velocity, and acceleration of an object. Without a frame of reference, it would be impossible to accurately describe and understand the motion of an object. Therefore, the statement that when describing motion, you are comparing it with some frame of reference is true.

    Rate this question:

  • 5. 

    Velocity is speed in a given direction.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The statement is true because velocity includes both the speed and direction of an object's motion. Speed is a scalar quantity that only measures how fast an object is moving, while velocity is a vector quantity that includes both speed and direction. Therefore, velocity is a more comprehensive measure of an object's motion compared to speed alone.

    Rate this question:

  • 6. 

    Change in position in a certain amount of time is called __________.

    Correct Answer
    Motion
    motion
    mOTION
    mOtIoN
    MoTiOn
    MOTION
    Explanation
    The correct answer is motion. Motion refers to the change in position of an object over a certain amount of time. The different capitalizations of the word do not affect its meaning or definition.

    Rate this question:

  • 7. 

    A force is a __________.

    • Push

    • Pull

    • The ability to change directions

    • All of the other answers

    Correct Answer
    A. All of the other answers
    Explanation
    The correct answer is "All of the other answers." This means that a force can be a push, a pull, or the ability to change directions. A force is any interaction that can cause an object to accelerate or change its motion. Pushing and pulling are common examples of forces, and the ability to change directions also involves the application of force. Therefore, all of the given options accurately describe what a force is.

    Rate this question:

  • 8. 

    Newton's __________ Law of Motion states that for every action, there is an equal an opposite reaction.

    • 1st

    • 2nd

    • 3rd

    • 4th

    Correct Answer
    A. 3rd
    Explanation
    Newton's 3rd Law of Motion states that for every action, there is an equal and opposite reaction. This means that when an object exerts a force on another object, the second object exerts a force of equal magnitude but in the opposite direction on the first object. This law explains the concept of forces and interactions between objects, emphasizing that forces always occur in pairs.

    Rate this question:

  • 9. 

    Looking at the Pacific Ocean, when the sun drops below the horizon of California is the sun falling or are you moving?

    • The sun is falling

    • You are moving

    Correct Answer
    A. You are moving
    Explanation
    The correct answer is "You are moving." When we observe the sun dropping below the horizon, it creates an illusion that the sun is falling. However, in reality, it is the Earth's rotation that causes the sun to appear to set. As the Earth rotates, it moves us away from the sun's direct rays, creating the illusion of the sun setting. Therefore, it is our movement that causes the sun to appear to set, rather than the sun actually falling.

    Rate this question:

  • 10. 

    How do you calculate the speed?

    • Divide time by distance

    • Divide distance by time

    • Multiply speed by time

    • Multiply time by distance

    Correct Answer
    A. Divide distance by time
    Explanation
    To calculate speed, you divide the distance traveled by the time taken. This is because speed is defined as the distance traveled per unit of time. By dividing distance by time, you can determine how much distance is covered in a specific amount of time, giving you the speed of an object or person.

    Rate this question:

  • 11. 

    The rate of change in velocity is acceleration

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Acceleration is defined as the rate of change in velocity over time. It measures how quickly an object's velocity is changing. Therefore, the statement "The rate of change in velocity is acceleration" is correct. When an object's velocity changes, it means that its speed or direction or both are changing, and this change is quantified by acceleration.

    Rate this question:

  • 12. 

    The formula for momentum is mass times velocity.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The formula for momentum is mass times velocity because momentum is defined as the product of an object's mass and its velocity. This means that the momentum of an object is directly proportional to both its mass and its velocity. As the mass or velocity of an object increases, its momentum also increases. Therefore, the statement "The formula for momentum is mass times velocity" is true.

    Rate this question:

  • 13. 

    A(n) __________ force is when two forces act in the same direction

    Correct Answer
    Unbalanced
    UNBALANCED
    uNbAlAnCeD
    UnBaLaNcEd
    unbalanced
    uNBALANCED
  • 14. 

    Friction is a force that acts in a direction the same/opposite of the motion.

    • The same

    • Opposite

    Correct Answer
    A. Opposite
    Explanation
    Friction is a force that opposes the motion of an object. When an object is in motion, the friction force acts in the opposite direction to the motion. This is because friction is caused by the interaction between the surfaces of two objects, which creates resistance and hinders the movement. Therefore, the correct answer is "Opposite."

    Rate this question:

  • 15. 

    Newton's __________ of Motion states that acceleration cannot occur without a force. This means that force and acceleration are related.

    • 1st

    • 2nd

    • 3rd

    • 4th

    Correct Answer
    A. 2nd
    Explanation
    The correct answer is the 2nd Law of Motion. This law, also known as Newton's second law, states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. In simpler terms, it means that a larger force will cause a larger acceleration, and a smaller force will cause a smaller acceleration. So, the statement that acceleration cannot occur without a force aligns with Newton's second law.

    Rate this question:

  • 16. 

    Friction causes a moving object to slow down and without it, you wouldn't be able to walk.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Friction is a force that opposes the motion of an object. When an object is in motion, friction acts in the opposite direction, causing the object to slow down. This is why we need friction to walk. When we take a step, the friction between our feet and the ground allows us to push off and move forward. Without friction, our feet would simply slide and we wouldn't be able to walk or maintain balance. Therefore, the statement is true.

    Rate this question:

  • 17. 

    Constant speed is the type of speed that changes in a given amount of time.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The given statement is incorrect. Constant speed is the type of speed that remains the same over a given amount of time, without any changes. It does not change in a given amount of time. Therefore, the correct answer is False.

    Rate this question:

  • 18. 

    The more __________ an object has, the harder it is to stop.

    Correct Answer
    Momentum
    momentum
    MOMENTUM
    mOMENTUM
    MoMeNtUm
    mOmEnTuM
    Explanation
    The correct answer is momentum. Momentum is a property of an object that depends on its mass and velocity. The greater the momentum an object has, the harder it is to stop because it would require more force or time to change its velocity. The variations in capitalization do not affect the concept of momentum.

    Rate this question:

  • 19. 

    Newton's __________ Law of Motion states that an object stays at rest and constant velocity, unless it is acted upon an unbalanced force.

    • 1st

    • 2nd

    • 3rd

    • 4th

    Correct Answer
    A. 1st
    Explanation
    Newton's 1st Law of Motion, also known as the law of inertia, states that an object will remain at rest or continue moving at a constant velocity unless acted upon by an unbalanced force. This means that if no external force is applied to an object, it will either remain stationary or continue moving in a straight line at a constant speed. The first law is often referred to as the law of inertia because it describes how an object's natural tendency is to resist changes in its motion.

    Rate this question:

  • 20. 

    A balanced force is calculated by using addition/subtraction.

    • Addition

    • Subtraction

    Correct Answer
    A. Subtraction
    Explanation
    A balanced force is calculated by using subtraction because when forces are balanced, their magnitudes are equal but their directions are opposite. When we subtract the force vectors, the magnitudes cancel each other out, resulting in a net force of zero. This indicates that the forces are balanced and there is no acceleration or change in motion.

    Rate this question:

  • 21. 

    Acceleration is speeding up, slowing down, or changing direction.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Acceleration is a measure of how quickly an object's velocity is changing. It can occur when an object is speeding up, slowing down, or changing direction. Therefore, the statement that acceleration is speeding up, slowing down, or changing direction is true.

    Rate this question:

  • 22. 

    What causes friction?

    • Objects and surfaces are perfectly smooth

    • Objects and surfaces are not perfectly smooth

    • It doesn't matter how smooth objects are

    Correct Answer
    A. Objects and surfaces are not perfectly smooth
    Explanation
    Friction is caused by the interaction between two objects or surfaces. When objects or surfaces are not perfectly smooth, their irregularities and roughness create resistance when they come into contact, leading to friction. The roughness causes the surfaces to interlock and create a force that opposes the motion between them. Therefore, the correct answer is that objects and surfaces are not perfectly smooth.

    Rate this question:

  • 23. 

    What is a frame of reference?

    • An ability to change the size of motion

    • Object or background from which movement is compared

    • A thing that rotates with the sun

    • Object or background which is compared with another object

    Correct Answer
    A. Object or background from which movement is compared
    Explanation
    A frame of reference refers to an object or background that is used as a point of comparison to observe and measure the motion of another object. It provides a fixed perspective or context to understand the movement of an object relative to its surroundings. By using a frame of reference, we can determine the speed, direction, and other characteristics of an object's motion.

    Rate this question:

  • 24. 

    If the distance of something is given and the speed is also given, how can you calculate the time?

    • Multiply distance by speed

    • Divide distance by speed

    • Divide speed by time

    • Multiply time by speed

    Correct Answer
    A. Divide distance by speed
    Explanation
    To calculate the time, you need to divide the distance by the speed. This is because time is equal to distance divided by speed according to the formula: time = distance / speed. By dividing the distance by the speed, you can determine how long it will take to cover that distance at the given speed.

    Rate this question:

  • 25. 

    Average speed is the type of speed that does not change in a given amount of time.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The given statement is incorrect. Average speed is the total distance traveled divided by the total time taken. It is not a fixed or constant speed, but rather a measure of the overall speed over a given period of time. Therefore, the correct answer is False.

    Rate this question:

  • 26.

    • Earth

    • Sun

    • Outer Space

    • Gravity

    Correct Answer
    A. Earth
    Explanation
    The most common frame of reference is the Earth because it is the planet that humans inhabit and use as a point of reference for most measurements and observations. It is the center of our daily lives and the basis for our understanding of time, space, and motion.

    Rate this question:

  • 27. 

    If the speed of something is given and the time is also given, how can you calculate the distance traveled?

    • Multiply time by distance

    • Divide distance by speed

    • Divide speed by time

    • Multiply speed by time

    Correct Answer
    A. Multiply speed by time
    Explanation
    To calculate the distance traveled, you need to multiply the speed by the time. This is because speed is defined as the distance traveled per unit of time. By multiplying the speed by the given time, you can determine the total distance covered during that period.

    Rate this question:

  • 28. 

    Velocity measures speed and acceleration.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    Velocity measures speed, but not acceleration. Velocity is a vector quantity that includes both the magnitude (speed) and direction of an object's motion. It is defined as the rate of change of displacement with respect to time. Acceleration, on the other hand, measures the rate of change of velocity with respect to time. It is a vector quantity that indicates how quickly an object's velocity is changing, either in magnitude or direction. Therefore, while velocity includes speed, it does not directly measure acceleration.

    The three types of friction are __________.

    • Rolling, Sliding and Fluid

    • Rolling, Sliding and Electric

    • Electric, Wood and Fusion

    • All of the other answers

    Correct Answer
    A. Rolling, Sliding and Fluid
    Explanation
    The correct answer is Rolling, Sliding and Fluid. These three types of friction are commonly observed in daily life. Rolling friction occurs when an object rolls over a surface, like a ball rolling on the ground. Sliding friction occurs when two surfaces slide against each other, like when you drag a chair across the floor. Fluid friction occurs when an object moves through a fluid, like air or water, and experiences resistance.

  • 30. 

    An unbalanced force is calculated by using addition/subtraction.

    • Addition

    • Subtraction

    Correct Answer
    A. Addition
    Explanation
    An unbalanced force is calculated by using addition because when multiple forces act on an object in different directions, their magnitudes and directions need to be added together to determine the overall effect on the object's motion. This is in accordance with Newton's second law of motion, which states that the net force acting on an object is equal to the mass of the object multiplied by its acceleration. By adding the individual forces, we can determine the resultant force and its direction, which will determine the object's acceleration.

    How is momentum conserved?

    • When both objects collide. Momentum is lost.

    • The objects getting inertia.

    • When both objects collide. None of the momentum is lost.

    • Only the fast and heavy objects have momentum.

    Correct Answer
    A. When both objects collide. None of the momentum is lost.
    Explanation
    When both objects collide, momentum is conserved, meaning that the total momentum before the collision is equal to the total momentum after the collision. This is because momentum is a vector quantity, and in a collision, it can be transferred between objects. While the individual momenta of the objects may change, the total momentum of the system remains constant. Therefore, none of the momentum is lost during the collision.

    Rate this question:

  • 32. 

    Why is velocity in circular motion continuously changing?

    • Acceleration is continuously changing

    • Direction is continuously changing, not velocity

    • Speed is continuously changing

    • Velocity is continuously changing, as well as direction

    Correct Answer
    A. Velocity is continuously changing, as well as direction
    Explanation
    In circular motion, the velocity is continuously changing because the direction of the motion is constantly changing. Even if the speed remains constant, the object is still changing its velocity because velocity is a vector quantity that includes both speed and direction. As the object moves in a circular path, it experiences a change in direction at every point, resulting in a continuously changing velocity.

    Rate this question:

  • 33. 

    What is distance?

    • The length between two places

    • The length between two points

    • The length between two areas

    • How far I am from somewhere

    Correct Answer
    A. The length between two places
    Explanation
    The correct answer is "The length between two places." This answer accurately defines distance as the measurement of length between two specific locations or areas. It distinguishes distance from other options such as points or areas, and also clarifies that it refers to the length between places rather than personal perspective or location.
