In physics, motion is the change in position of an object with respect to time. It is mathematically described in terms of displacement, distance, velocity, acceleration, speed, and frame of reference to an observer, measuring the change in position of the body relative to that frame with a change in time. The branch of physics describing the motion of objects without reference to their cause is called kinematics, while the branch studying forces and their effect on motion is called dynamics. Motion can be translational, rotational, linear, periodic, or oscillatory, depending on the type of force acting on the body
. In general, motion signifies a continuous change in the position or configuration of a physical system in space
