This type of force resist motion between two surfaces that are pressed together

• contact
• gravity
• friction

If the net force is equal to zero, the forces acting on the object are

• balanced

• unbalanced

Balanced forces do not change the objects speed or 

• direction
• distance 
• time
• mass
