What is an example of action and reaction forces in a balloon?

Back

Front

If a person pushes against a wall, what happens?

Back

The wall pushes back with an equal and opposite force.

Front

What is the relationship between action and reaction forces?

Back

They are always equal in magnitude and opposite in direction.

Front

Can action and reaction forces cancel each other out?

Back

No, they act on different objects and do not cancel each other.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.
