why does a body move when something strikes it?
when a moving object strikes a stationary one, then the force of the impact on the object struck continues on to the opposite side of the side that was hit. the moving object is only affected by the side of the impact, which also corresponds with its direction of movement. this object stays where it is and gives up all momentum. the object that was hit moves in the direction of the force which is now continued in and through it, and continues to move until the force of this movement is exhausted. the movement exhausts itself because there is no permanent force being applied to the object that was hit.
