When the net force is zero, the body must be at rest or must be moving at a constant velocity (constant speed and direction), by Newton's first law . If the net force is not zero, then the body is accelerating in that direction according to Newton's second law . </P>

State two components common to all forces. how are these indicated in a diagram
