Question

what is acceleration.how can you calculate it​

Answer 1

Acceleration has the dimensions of velocity (L/T) divided by time, i.e. L T−2. 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. SI unit: m/s2, m·s−2, m s−2.
