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: -It is a vector quantity, which means we need both magnitude (speed) and direction to define velocity. The SI unit of it is metre per second (ms-1). If there is a change in magnitude or the direction of the velocity of a body, then it is said to be accelerating.

Detailed explanation-3: -in acceleration, we want to know the change in velocity. Velocity is measured in m/s. So we put acceleration as m/s per second. Using simple math, we come up with the unit m/s^2.

Detailed explanation-4: -Because acceleration is velocity in m/s divided by time in s, the SI units for acceleration are m/s2, meters per second squared or meters per second per second, which literally means by how many meters per second the velocity changes every second. Was this answer helpful?

Detailed explanation-5: -Hence, the mks units of velocity are meters per second: (1) Here, stands for a velocity, for a length, and for a time, whereas the operator represents the units, or dimensions, of the quantity contained within the brackets. Momentum can be reduced to a mass times a velocity.
