Newtons 3rd Law

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 magnitude and opposite in direction.

Front

Why do action-reaction forces not cancel each other out?

Back

They act on different objects.

Front

In a force pair, how are the forces directed?

Back

The forces are in opposite directions.

Front

What happens to a balloon when the air is released?

Back

The balloon goes up due to the reaction force of the air escaping.

Front

Can you give an example of Newton’s Third Law?

Back

A swimmer pushes water backward, and the water pushes the swimmer forward.

Front

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

Back

Walking: your foot pushes down on the ground, and the ground pushes your foot up.

Front

How do action-reaction forces relate to motion?

Back

They are responsible for the motion of objects as they interact.

Front

What is the significance of the equal force in action-reaction pairs?

Back

It ensures that the forces do not change the momentum of the system as a whole.

Front

What is the relationship between mass and acceleration in Newton's laws?

Back

According to Newton's Second Law, force equals mass times acceleration (F=ma).
