Newton's 3rd Law of Motion Practice

Front

What does Newton's 3rd Law of Motion state?

Back

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

Front

What happens when an object exerts a force on another object according to Newton's 3rd Law?

Back

The second object exerts an equal amount of force in the opposite direction.

Front

How does a swimmer move forward when paddling?

Back

As the swimmer's hands push the water backward, the water pushes forward on the swimmer.

Front

In a collision between a heavy football player and a light football player, who exerts more force?

Back

They both exert an equal amount of force.

Front

Why does it hurt to punch a wall?

Back

When your fist hits the wall, the wall exerts an equal force back onto your fist.

Front

What is an example of Newton's 3rd Law in action?

Back

When two objects collide, they exert equal forces on each other.

Front

What is the relationship between action and reaction forces?

Back

Action and reaction forces are equal in magnitude and opposite in direction.

Front

Can a small object exert a large force?

Back

Yes, if it accelerates quickly, it can exert a large force despite its small mass.

Front

What is inertia and how does it relate to Newton's laws?

Back

Inertia is the tendency of an object to resist changes in its state of motion, which is explained by Newton's 1st Law.

Front

How does Newton's 3rd Law apply to rocket propulsion?

Back

Rockets push exhaust gases backward, and in response, the rocket is propelled forward.
