What are the standard units of acceleration?
A
m
B
s
C
m s-1
D
m s-2
Explanation: 

Detailed explanation-1: -, or less commonly, as m/s/s. As acceleration, the unit is interpreted physically as change in velocity or speed per time interval, i.e. metre per second per second and is treated as a vector quantity.

Detailed explanation-2: -Unit of acceleration is the metre per second per second (m/s2). Definition. The snewton is that force which, when acting on a mass of one kilogramme, produces an acceleration of one metre per second per second.

Detailed explanation-3: -The SI unit of velocity is ms−1 and SI unit of time is seconds. Therefore, SI unit of acceleration is ms−2.

Detailed explanation-4: -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-5: -The SI unit of acceleration is the metre per second squared (m s−2); or “metre per second per second", as the velocity in metres per second changes by the acceleration value, every second.
