... If a bicycle and a parked car have a head-on collision, the force of impact is greater on the bicycle. A quantity that has both magnitude and direction is called a scalar. When all forces acting on an object are balanced, the object is said to be in equilibrium. Momentum is defined as an object's ma ...
