what is motion
Nelson Reply
In physics, motion is the change in position of an object with respect to its surroundings in a given interval of time. Motion is mathematically described in terms of displacement, distance, velocity, acceleration, time, and speed. ... Momentum is a quantity which is used for measuring the motion of
