A ball is a body and in Physics a body is a delimited portion of matter and can be made from one or more substances.
A body can be in different states of movement: in rest state or in motion state.To determine the state of rest or motion in which a body may be it is necessary to determine the position in space and timing in which is it held in that position.
A body is moving in a certain time frame,if there are different moments in that period of time, in which the body occupies different positions from the referrence body.
Knowing that we can say that a ball can be moved if we can act with a force that make the ball to change its original position and to be in a state of movement from a chosen point of referrence.
