Front

What is Newton's Third Law of Motion?

Back

For every action, there is an equal and opposite reaction.

What force is acting on an object that is falling towards the ground?

Back

Gravity.

Front

What happens to the boat when a person steps out onto the dock?

Front

What is the relationship between mass and force in Newton's Third Law?

Back

The mass of an object does not affect the equality of action and reaction forces.

Front

What is an example of friction as a force?

Back

Friction opposes the motion of sliding objects.
