Front

How do you find the net force when two forces are in the same direction?

Back

You add the forces together.

Front

What are three ways to describe motion?

Back

Speed, Direction, Position.

Front

What happens to an object at rest when balanced forces act on it?

Unbalanced forces can change the speed or direction of the moving object.

Front

What is friction?

Back

Friction is a force that opposes motion between two surfaces in contact.

Front

What is gravity?

Back

Gravity is a force that pulls objects toward each other, such as the Earth pulling objects toward its center.
