Net Forces

Front

What is a force?

Back

A force is the PUSH or PULL on an object.

Front

What is a balanced force?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.

Front

What is an unbalanced force?

Back

Unbalanced forces are not equal and can cause an object to start moving, stop moving, or change direction.

Front

What is net force?

Back

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

Front

If two people push a couch with 20 N to the right and 20 N to the left, what is the net force?

Back

0 N (the forces cancel each other out).

Front

If a force of 30 N is applied to the right and a force of 10 N is applied to the left, what is the net force?

Back

20 N to the right.

Front

What happens when the net force on an object is zero?

Back

The object remains at rest or continues to move at a constant speed in a straight line.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

What is the effect of an unbalanced force on an object?

Back

An unbalanced force can cause an object to accelerate, decelerate, or change direction.

Front

If a 50 N force is applied to the right and a 20 N force is applied to the right, what is the net force?

Back

70 N to the right.
