Web. Velocity is a measure of how quickly any given object moves. So, it can be defined as the change in the position of an object, divided by time. Velocity has a magnitude (a value) as well as a direction. The unit for velocity is meters per second (meter/second).. Velocity is the rate of change of position with respect to time, whereas acceleration is the rate of change of velocity. Both are vector quantities (and so also have a specified direction), but the units of velocity are meters per second while the units of acceleration are meters per second squared. The reason behind this is that Earth has a velocity perpendicular to the gravitational force exerted by the Sun. Thus, the planets move sideways in addition to getting attracted by the Sun, which keeps them moving in specified orbits.. Speed is not the same as velocity. Speed has the dimensions of distance divided by time. The SI unit of speed is the metre per second (m/s), but the most common unit of speed in everyday usage is the kilometre per hour (km/h) or, in the US and the UK, miles per hour (mph).. Web. Linear Velocity. Angular velocity is defined as the rate of change of the angular position of a rotating body. Linear velocity is defined as the rate of change of displacement with respect to time when the object moves along a straight path.
