Net Force

Front

What is net force?

Back

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

Front

If two forces act in the same direction, how do you find the net force?

Back

Add the magnitudes of the two forces together.

Front

What happens when two forces of equal magnitude act in opposite directions?

Back

The net force is zero, and the object does not move.

Front

What is friction?

Back

A force that opposes motion between two surfaces that are in contact.

Front

If a couch is pushed with 35 N to the right and there is 10 N of friction to the left, what is the net force?

Back

25 N to the right.

Front

What is a force?

Back

A push or pull that can cause an object to move or change its motion.

Front

If you pull with 20 N to the left and your friend pulls with 20 N to the right, what is the net force?

Back

0 N, the forces cancel each other out.

Front

What is the unit of force?

Back

Newton (N).

Front

How do you calculate net force when multiple forces are acting on an object?

Back

Add all the forces acting in one direction and subtract the forces acting in the opposite direction.

Front

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

Back

The object will remain at rest or continue to move at a constant speed.
