Newton's 3rd Law

Front

What is Newton's Third Law of Motion?

Back

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

Front

What is an action force?

Back

An action force is the initial force exerted by one object on another.

Front

What is a reaction force?

Back

A reaction force is the force exerted by the second object back on the first object, equal in size and opposite in direction to the action force.

Give an example of Newton's Third Law in everyday life.

Back

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

Front

What happens when a foot kicks a ball?

Back

The foot exerts a force on the ball (action), and the ball exerts an equal and opposite force back on the foot (reaction).

Front

How does the force of a bat hitting a baseball compare to the force of the baseball hitting the bat?

Back

The force of the bat hitting the ball is equal to the force of the ball hitting the bat.

Front

What is the importance of the reaction force in sports?

Back

Reaction forces help athletes understand how to use their movements effectively, such as in jumping or throwing.

Front

What does it mean for forces to be 'equal and opposite'?

Back

It means that the forces are the same in strength but act in opposite directions.

Front

How can understanding Newton's Third Law help in designing safer products?

Back

Designers can create products that distribute forces more evenly, reducing the impact on any single point.

Front

What is an example of action and reaction in nature?

Back

When a bird flaps its wings down (action), it pushes air down and moves upward (reaction).
