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).

• A car accelerating on a highway

• A book resting on a table

• A ball rolling down a hill

• A plane taking off

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

• Pushing a bicycle

• Lifting a feather

• Pushing a car

• Throwing a paper airplane

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

• A rocket launching

• A ball sitting on the ground

• A leaf falling from a tree

• A car parked on a hill
