Questions and Answers

Which word defines the total distance traveled divided by the total time elapsed?
- A.
Velocity
- B.
Average speed
- C.
Acceleration
- D.
Motion
Correct Answer
B. Average speedExplanation
Average speed is defined as the total distance traveled divided by the total time elapsed. It represents the overall rate at which an object moves over a given period of time, regardless of the direction. Velocity, on the other hand, includes both the speed and direction of an object's motion. Acceleration refers to the rate at which an object's velocity changes. Motion is a general term that encompasses any change in an object's position over time.Rate this question:

Which term defines the speed of an object in a certain direction?
- A.
Velocity
- B.
Average speed
- C.
Acceleratoin
- D.
Motion
Correct Answer
A. VelocityExplanation
Velocity is the term that defines the speed of an object in a certain direction. It not only considers the magnitude of the speed but also the direction in which the object is moving. Therefore, velocity is the correct answer to this question.Rate this question:

Which term defines a change in position relative to a reference point?
- A.
Veloctiy
- B.
Average speed
- C.
Acceleration
- D.
Motion
Correct Answer
D. MotionExplanation
Motion is the term that defines a change in position relative to a reference point. It refers to the movement or displacement of an object or person from one place to another. Motion can be described in terms of speed, direction, and time, and it is a fundamental concept in physics and everyday life.Rate this question:

Which term that defines the rate at which velocity changes over time?
- A.
Motion
- B.
Acceleration
- C.
Average speed
Correct Answer
B. AccelerationExplanation
Acceleration is the term that defines the rate at which velocity changes over time. Velocity is the rate at which an object's position changes over time, and acceleration measures how quickly that velocity is changing. If an object's velocity is increasing, it is said to be accelerating. If an object's velocity is decreasing, it is said to be decelerating or experiencing negative acceleration. Average speed, on the other hand, is a measure of how fast an object is moving overall, but it does not take into account the changes in velocity over time.Rate this question:

Which of the following best represents acceleration as presented on a graph?
- A.
Motion versus time
- B.
Distance versus time
- C.
Speed versus time
- D.
Reference point versus time
Correct Answer
C. Speed versus timeExplanation
Acceleration is defined as the rate of change of velocity with respect to time. Velocity is the rate at which an object changes its position, so speed represents the magnitude of velocity. Therefore, the best representation of acceleration on a graph would be speed versus time, as it shows how the speed of an object changes over a specific time interval.Rate this question:

Which of the following most closely illustrates motion by relating it to a reference point?
- A.
The hands of a clock relative to the numbers on the clock
- B.
The velocity change of a train relative to time
- C.
the speed of a bicycle relative to the direction of travel
Correct Answer
A. The hands of a clock relative to the numbers on the clockExplanation
The hands of a clock relative to the numbers on the clock illustrate motion by showing the position of the hands in relation to a fixed reference point, which is the numbers on the clock. As the hands move, they indicate the passage of time and their position changes relative to the numbers, allowing us to measure the time accurately. This demonstrates how motion can be understood and measured by comparing it to a reference point.Rate this question:

What causes a change in velocity?
- A.
A change in speed, a change in distance, or both
- B.
A change in speed, a change in direction, or both
- C.
A change in speed, a change in time, or both
- D.
a change in speed, a change in motion, or both
Correct Answer
B. A change in speed, a change in direction, or bothExplanation
When there is a change in velocity, it means that the object is experiencing a change in its speed and/or direction of motion. This can occur when the object speeds up or slows down (change in speed), changes its path or turns (change in direction), or both. Therefore, a change in velocity can be caused by a change in speed, a change in direction, or both.Rate this question:

Which of the following are the two factors used to calculate average speed?
- A.
Total distance and total time
- B.
Motion and time
- C.
velocity and time
- D.
Total acceleration and total time
Correct Answer
A. Total distance and total timeExplanation
Average speed is calculated by dividing the total distance traveled by the total time taken. This is because average speed is a measure of how fast an object is moving over a given period of time, and it is determined by the total distance covered and the total time taken to cover that distance. Factors such as motion, velocity, acceleration, and time are not directly used in calculating average speed.Rate this question:

Please fill answer below. In science, a push or a pull exerted on an object is called a(n)_________.
Correct Answer
forceExplanation
In science, a push or a pull exerted on an object is called a force. A force is a physical interaction that can cause an object to accelerate, change its shape, or change its state of rest or motion. It is a fundamental concept in physics and is measured in units such as Newtons. Forces can be applied in various ways, such as through direct contact or through fields like gravity or magnetism.Rate this question:

The SI unit for force is called_____.
- A.
Meter
- B.
Newton
- C.
Liter
- D.
Motion
Correct Answer
B. NewtonExplanation
The SI unit for force is called newton. The newton is defined as the amount of force required to accelerate a one kilogram mass by one meter per second squared. It is named after Sir Isaac Newton, who made significant contributions to the field of physics and formulated the laws of motion. The newton is widely used in scientific calculations and is the standard unit for measuring force in the International System of Units (SI).Rate this question:

Which of the following cause an object to start moving?
- A.
Balanced forces
- B.
Either balanced or unbalanced forces
- C.
unbalanced forces
- D.
Any combination of forces
Correct Answer
C. unbalanced forcesExplanation
Unbalanced forces cause an object to start moving. When the forces acting on an object are unbalanced, meaning that they are not equal in magnitude and opposite in direction, there is a net force acting on the object. This net force causes the object to accelerate in the direction of the larger force, resulting in the object starting to move. Balanced forces, on the other hand, do not cause any change in the object's motion as they cancel each other out.Rate this question:

When the net force on an object equals 0 N, the forces are which of the following?
- A.
Balanced
- B.
Unbalanced
- C.
A pull
- D.
A push
Correct Answer
A. BalancedExplanation
When the net force on an object equals 0 N, it means that the forces acting on the object are balanced. This means that the forces are equal in magnitude and opposite in direction, resulting in a net force of zero. In this situation, the object will remain at rest or continue to move at a constant velocity. The forces being balanced indicate that there is no overall force acting on the object, resulting in a state of equilibrium.Rate this question:
