Net Force and Newton's Third Law Test Review

Front

What is net force?

Back

The overall force acting on an object when all the individual forces are combined.

Front

What is the unit of force?

Back

Newton (N)

Front

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

Back

The net force is zero.

Front

What is a force?

Back

A PUSH or PULL on an object.

Front

What is the effect of a net force of 0 N on an object?

Back

The object does not move.

Front

If a 10 N force is applied to the right and a 10 N force is applied to the left, what is the net force?

Back

0 N; the forces cancel each other out.

Front

What is the net force if a 5 N force is applied to the right and a 3 N force is applied to the left?

Back

2 N to the right.

Front

How do you calculate net force?

Back

Add all forces acting on an object, taking direction into account.

Front

What is Newton's Third Law of Motion?

Back

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

Front

What is an example of Newton's Third Law?

Back

When you push against a wall, the wall pushes back with equal force.
