What does it mean for forces to occur in pairs?

Back

For every force exerted, there is a force of equal magnitude and opposite direction acting on a different object.

Front

Is gravity and air resistance an action-reaction pair?

Back

No, because both forces act on the same object (the skydiver).

Front

What is an action-reaction pair?

Back

Two forces that are equal in size, opposite in direction, and act on different objects.

What is an example of an action-reaction pair in everyday life?

Back

When you jump off a small boat, you push the boat backwards as you move forward.

Front

What is the significance of Newton's Third Law in sports?

Back

It explains how athletes use forces to propel themselves or objects, like a basketball player jumping off the ground.
