What is an example of action and reaction forces in everyday life?

Back

When you sit on a chair, your body exerts a downward force on the chair (action), and the chair exerts an upward force on your body (reaction).

What happens to the forces when a bat hits a baseball?

Back

The bat exerts a force on the baseball (action), and the baseball exerts an equal and opposite force on the bat (reaction).

Can action and reaction forces act on the same object?

Back

No, they act on different objects.

How does Newton's Third Law explain the motion of a balloon when air is released?

Back

The air pushes out of the balloon (action), and the balloon moves in the opposite direction (reaction).
