Newton's Third Law

Front

What does Newton's Third Law of Motion state?

Back

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

Front

If a person on a skateboard throws a heavy object, in which direction will they move?

Back

They will move in the opposite direction of the thrown object.

Front

What is an action-reaction pair?

Back

A pair of forces acting on two different objects where one force is the action and the other is the reaction.

Front

Is gravity pulling a skydiver down and air friction pushing them up an action-reaction pair?

Back

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

Front

What happens to the forces when two objects collide according to Newton's Third Law?

Back

The forces are equal in magnitude and opposite in direction.

Front

Define opposing force in the context of Newton's Third Law.

Back

An opposing force is a force that acts in the opposite direction with the same strength.

Front

What is 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

How does Newton's Third Law apply to rocket propulsion?

Back

Rockets push exhaust gases downward (action), and in response, the rocket moves upward (reaction).

Front

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

Back

It means that the forces exerted by two objects on each other are of the same strength.

Front

Can you give an example of an action-reaction pair?

Back

When a swimmer pushes water backward (action), the swimmer moves forward (reaction).
