Newton's Third Law: Action/Reaction Forces

Front

What is Newton's Third Law of Motion?

Back

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

Front

Define action and reaction force pairs.

Back

Action and reaction force pairs are forces that are equal in size, opposite in direction, and act on different objects.

Front

What happens when a cannon fires a cannonball?

Back

The cannonball pushes back on the cannon with an equal and opposite force.

Front

Explain why action and reaction forces do not cancel each other out.

Back

They act on different objects, so they do not cancel each other out.

Front

What is an example of action and reaction forces in sports?

Back

When a player pushes off the ground to jump, the ground pushes back with an equal and opposite force.

Front

What occurs when a person jumps off a canoe?

Back

The canoe moves backward in the opposite direction of the jump due to the reaction force.

Front

How does gravitational attraction demonstrate Newton's Third Law?

Back

When a book is pulled down by gravity, it also pulls up on the Earth with an equal force.

Front

What is the significance of action and reaction forces in understanding motion?

Back

They help explain how objects interact and move in response to forces.

Front

Can action and reaction forces be in equilibrium?

Back

No, action and reaction force pairs can never cause equilibrium.

Front

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

Back

When you sit in a chair, your body exerts a downward force on the chair, and the chair exerts an equal upward force on you.
