Detailed explanation-1: -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.
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: -Since we are using metres and seconds as our basic units, we will measure acceleration in metres per second per second. This will be abbreviated as m/s2. It is also commonly abbreviated as ms−2.
Detailed explanation-4: -(b) Acceleration has the SI unit of m/s2.
