Newton's Third Law: Action-Reaction

Front

What is Newton's Third Law of Motion?

Back

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

Front

What happens when an object is pushed?

Back

It always pushes back with an equal and opposite force.

Front

In the action-reaction pair, what is the reaction when a cannon pushes on a cannonball?

Back

The cannonball pushes back on the cannon.

Front

True or False: According to Newton's third law, forces come in pairs.

Back

True.

Front

How do the forces between a ball and a person's head demonstrate Newton's Third Law?

Back

Both the ball and the head are exerting equal force on each other.

Front

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

Back

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

Front

What does 'equal and opposite' mean in the context of forces?

Back

It means that forces exerted by two objects on each other are equal in size but opposite in direction.

Front

If a swimmer pushes the water backwards, what happens to the swimmer?

Back

The swimmer moves forward due to the reaction force of the water pushing back.

Front

What is the significance of action-reaction pairs in sports?

Back

They explain how athletes can move and change direction by exerting forces on the ground or equipment.

Front

Can you give an example of Newton's Third Law in action with a rocket?

Back

A rocket pushes exhaust gases downwards, and in reaction, the rocket moves upwards.
