Front

Force always comes in __________.

Back

pairs.

Front

Why is the net force 0 in the image?

Back

Because they are both pulling the same amount of force in opposite directions.

Front

Action-reaction forces never cancel each other out because __________.

Back

They act on different objects.

Front

Action-reaction pairs can cause a change in motion. True or False?

Back

True.

Front

How is this an example of Newton’s Third law?

Back

They are both exerting an equal force on each other.

Front

What is Newton's Third Law of Motion?

Back

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

Front

What are action-reaction force pairs?

Back

Forces that two objects exert on each other that are equal in size and opposite in direction.

Front

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 to the net force when two equal forces act in opposite directions?

Back

The net force is zero.

Front

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

Back

They explain how athletes can push off the ground to jump or sprint.
