Front

What is force?

A push or a pull.

Front

What is net force?

Back

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

Front

What are balanced forces?

Back

Forces that are equal in size and opposite in direction, resulting in no change in motion.

Front

What are unbalanced forces?

Back

Forces that are not equal and can cause a change in motion.

Front

If a girl pulls a rope with a force of 200 N to the left and two boys pull with a combined force of 100 N to the right, what is the net force?

Back

100 N to the left.

Front

If a person lifts a book with a force of 50 N and gravity pulls down with 15 N, what is the net force?

Back

35 N up.

Front

What happens when the net force is zero?

Back

The object remains at rest or continues to move at a constant velocity.

Front

What is the unit of force?

Back

Newton (N).

Front

How do you calculate net force when two forces act in the same direction?

Back

Add the magnitudes of the forces.

Front

How do you calculate net force when two forces act in opposite directions?

Back

Subtract the smaller force from the larger force.
