The branch of mechanics which deals with the motion of objects is called kinematics. If a body does not change its position, it is said to be on rest and if it changes its position it is known as motion. The examples of motion include: running, cycling, jumping, swimming, eating, drinking, playing, writing, typing, moving cars, throwing ball. The examples of rest include: sleeping, sitting, standing, staring, lying, a fixed clock, bottle kept on a table, a stopped car.
