Newtons 3rd Law

Front

What is Newton's 3rd Law of Motion?

Back

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

If a book exerts a force of 5N on a table, what force does the table exert back?

Back

5N, in the opposite direction.

Front

What are action-reaction forces?

Back

Forces that occur in pairs; when one object exerts a force on another, the second object exerts an equal and opposite force on the first.

Front

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

Back

Because they act on different objects.

What happens to a balloon when the air is released?

Back

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

Front

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

Back

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

Front

What does it mean when we say forces come in pairs?

Back

It means that every force has a corresponding force that is equal in size but opposite in direction.

Front

Can action-reaction forces act on the same object?

Back

No, they act on different objects.

Front

What is the relationship between action and reaction forces?

Back

They are equal in magnitude and opposite in direction.

Front

If a small car pushes a big truck, what happens?

Back

The truck pushes back on the car with an equal and opposite force.
