? Linear speed is the rate of change of a body’s position in a given direction with respect to time. It is measured in units of distance per unit of time, such as miles per hour or meters per second. Angular speed, also known as rotational speed, is the rate of change of an object’s angular position with respect to time. It is usually measured in degrees (or radians) per second. An example of angular speed is the speed of the earth rotating on its axis, which is about 15 degrees per hour.
