Detailed explanation-1: -Therefore, velocity is expressed in metres/second or m/s. The SI unit of velocity is metre per second (m/s). Alternatively, the velocity magnitude can also be expressed in centimetres per second (cm/s).
Detailed explanation-2: -Since the derivative of the position with respect to time gives the change in position (in metres) divided by the change in time (in seconds), velocity is measured in metres per second (m/s).
Detailed explanation-3: -Velocity can be measured directly, using a flowmeter (essentially a speedometer for water, Fig. 3.8 and Section 3.1.
Detailed explanation-4: -Velocity has units of displacement divided by time. In the lab, we will usually measure velocity in units of m/s. Velocity is also measured in km/h (and even in mi/hr).
