Linear Motion is the change of position from one place to another in a straight line and in one dimension. The two types of linear motion are uniform linear motion and non-uniform linear motion. Uniform linear motion is motion with constant speed(zero acceleration), while non-linear motion is motion with variable speed and the acceleration\u002Fdeceleration is not equal to zero.
