 Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which is an example of a unit used for velocity?
 A mph west B m/s south C km/hr east D All of the above
Explanation:

Detailed explanation-1: -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: -Units of Velocity The SI (international) units for velocity are m/s (meters per second), but velocity may also be expressed in any units of distance per time. Other units include miles per hour (mph), kilometers per hour (kph), and kilometers per second (km/s).

Detailed explanation-3: -Velocity is defined as the rate of change of distance of a body with respect to time. Its unit in SI is m/s.

Detailed explanation-4: -"The distance covered by a body in a unit time in a particular direction is called velocity.” Formula. Velocity = Displacement/Time. or V = S/t, SI unit of velocity is metre per second.

Detailed explanation-5: -Velocity is a vector quantity. For Example :25km/hr towards north. The direction of velocity is same as the direction of displacement of the body.
