A set of forces that cancel one another out is called a:

• balanced force

• unbalanced force

A set of forces acting on an object that do NOT cancel one another out is called a:

• balanced force

• unbalanced force

• balanced force

• unbalanced force

• net force

When the forces acting on an object are going in the OPPOSITE direction what do you do?

• ADD

• SUBTRACT

When the forces that are acting on an object are going in the SAME direction what do you do?

• ADD

• SUBTRACT
