The force that always acts opposite to the direction of the motion of an object is called:
-
Gravity
-
Inertia
-
Friction
-
None of the above
Correct Answer
A. FrictionExplanation
Friction is the force that always acts opposite to the direction of the motion of an object. When two surfaces are in contact, friction opposes the relative motion between them. It is caused by the interaction between the irregularities on the surfaces, which creates resistance to the motion. Friction plays a crucial role in everyday life, as it allows us to walk, drive, and hold objects. It is responsible for stopping or slowing down moving objects and is essential for stability and control.Rate this question:

According to Newton's third law, forces always occur in ____ pairs.
-
Equal but complementary
-
Equal but opposite
-
Unequal but opposite
-
Unequal but complementary
Correct Answer
A. Equal but oppositeExplanation
According to Newton's third law, forces always occur in equal but opposite pairs. This means that for every action force, there is an equal and opposite reaction force. This principle states that the force exerted by one object on another is always met with an equal force in the opposite direction exerted by the second object on the first. This law helps explain the concept of balanced forces and the conservation of momentum.Rate this question:

Newton first described gravity while watching:
-
Smoke rise
-
A car accelerate
-
Someone walking
-
An apple falling
Correct Answer
A. An apple fallingExplanation
Newton first described gravity while watching an apple falling. This observation led him to formulate the theory of gravity, which states that every object in the universe attracts every other object with a force that is directly proportional to their masses and inversely proportional to the square of the distance between them. This discovery revolutionized our understanding of the natural world and laid the foundation for modern physics.Rate this question:

You would NOT use _____ to find the acceleration of an object.
-
Initial speed
-
Final speed
-
Weight
-
Time
Correct Answer
A. WeightExplanation
Weight is a measure of the force of gravity acting on an object. Acceleration is determined by factors such as initial speed, final speed, and time. Weight can affect acceleration indirectly through the force of gravity, but it is not a direct measure of acceleration. Therefore, weight is not used to find the acceleration of an object.Rate this question:

Newton's _____ law of motion explains why you may lean sideways in a car if the driver turns a corner too quickly.
-
First
-
Second
-
Third
-
Primary
Correct Answer
A. FirstExplanation
Newton's first law of motion, also known as the law of inertia, states that an object at rest will stay at rest and an object in motion will stay in motion with the same speed and direction, unless acted upon by an external force. In the case of a car turning a corner too quickly, the car and its occupants are subject to a change in direction. According to Newton's first law, the occupants of the car will continue moving in a straight line due to their inertia. As a result, they will lean sideways in the car as their bodies resist the change in direction.Rate this question:

____ is the speed of an object and the direction of motion.
-
Friction
-
Mass
-
Gravity
-
Velocity
Correct Answer
A. VelocityExplanation
Velocity is the correct answer because it is defined as the speed of an object along with the direction of its motion. It is a vector quantity that takes into account both magnitude (speed) and direction, making it a comprehensive measure of an object's motion. Friction, mass, and gravity are not directly related to the speed and direction of an object's motion, making them incorrect answers.Rate this question:

_____ is NOT a force.
-
Friction
-
Gravity
-
Mass
-
Tension
Correct Answer
A. MassExplanation
Mass is not a force because it is a measure of the amount of matter in an object, not a force itself. Forces, such as friction and gravity, act upon objects with mass, but mass itself does not exert a force. Instead, it determines how an object responds to the forces acting upon it, such as acceleration or resistance to motion.Rate this question:

An object that experiences a push or a pull has a(n) __________ exerted on it.
-
Environment
-
Inertia
-
System
-
Force
Correct Answer
A. ForceExplanation
When an object experiences a push or a pull, it is being acted upon by a force. Force is a vector quantity that describes the interaction between two objects and can cause a change in the object's motion or shape. It is the force that causes the object to accelerate or decelerate, and it is measured in units of Newtons (N). Therefore, the correct answer is force.Rate this question:

Jack pushes a box of books across the floor. What causes the box to move?
-
A force
-
Friction
-
Gravity
-
Inertia
Correct Answer
A. A forceExplanation
The box of books is able to move because of a force. A force is a push or a pull that can cause an object to change its motion. In this case, Jack is exerting a force on the box by pushing it, which causes the box to move across the floor.Rate this question:

A magazine rests on top of a TV remote that is sitting on a table. Which is NOT exacting a force on the remote?
-
Gravity
-
Table
-
Magazine
-
The table
-
Your hand
Correct Answer
A. Your handExplanation
The hand is not exerting a force on the remote because it is not in contact with it. The other options, such as gravity, the table, and the magazine, are all exerting forces on the remote either through direct contact or through the force of gravity.Rate this question:
