Newton's Laws of Motion Quiz

Describe an example of Newton’s 1st Law of Motion (the motion of an object remains the same unless it is acted upon by a force).

• An example of this is a ball bouncing. You throw it down on the ground with a force, and it bounces back with an equal force.

• If a ball is still, it will remain still until a force, such as a kick, makes it move.

• pushing a car or pushing a shopping cart. You would need much more force to push a car the same distance as a shopping cart.

Describe an example of Newton’s 2nd Law of Motion (heavier objects need more force than lighter objects to make them move).

• An example of this is a ball bouncing. You throw it down on the ground with a force, and it bounces back with an equal force.

• If a ball is still, it will remain still until a force, such as a kick, makes it move.

• pushing a car or pushing a shopping cart. You would need much more force to push a car the same distance as a shopping cart.

Describe an example of Newton’s 3rd Law of Motion (for every action there is an equal and opposite reaction).

• An example of this is a ball bouncing. You throw it down on the ground with a force, and it bounces back with an equal force.

• If a ball is still, it will remain still until a force, such as a kick, makes it move.

• pushing a car or pushing a shopping cart. You would need much more force to push a car the same distance as a shopping cart.

A __________ force is when two forces cancel each other out and do not affect the motion of an object.

• balanced

• unbalanced

An __________ force results when one force is stronger than other forces and the motion of an object is affected.

• balanced

• unbalanced
