The net force is known as the unbalanced force or the resultantforce.When a force acts on an object, the effect can change the1.size,2.shape,3.stationary state,4.speed and5.direction of the object.__________________________________________________________Newton's Second LawThe rate of change of momentum of a body is directly proportional to the resultantforce acting on the body and is in the same direction.Implication: When there is resultant force acting on an object, the object willaccelerate (moving faster, moving slower or ch ...
