Change in velocity and time taken

Acceleration is the ratio between change in velocity and time taken and can be expressed as

a = dv/dt (1)

where

a = acceleration (m/s², ft/s²)

dv = change in velocity (m/s, ft/s)

t = time taken (s)

Example - Motorcycle Acceleration

If a motorcycle change velocity from 0 km/h to 100 km/h in 3 seconds, the acceleration can be calculated as

a = ((100 (km/h) - 0 (km/h)) 1000 (m/km) / 3600 (s/h)) / 3 (s)

    = 9.26 m/s²

or close to  acceleration of gravity 1 g = 9.81 m/s².
