Car Acceleration

Calculate acceleration of car

Sponsored Links

If you know the initial and final velocity of a car (or whatever) - and the time used - the average acceleration can be calculated as

a = dv / dt                                             (1)

where

a = acceleration of object (m/s2, ft/s2)

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

dt = time used (s)

Common benchmark velocities for acceleration of cars and motorcycles are

  • 0 - 60 mph = 0 - 26.8 m/s = 0 - 96.6 km/h
  • 0 - 100 km/h = 0 - 27.8 m/s = 0 - 62.1 mph

If you know the distance moved and the time used - the acceleration can be calculated as

a = 2 ds / dt2                                 (2)

where

ds = distance moved (m, ft)

Acceleration of some known cars

Acceleration Force

The acceleration force can be calculated as

F = m a                                (3)

where 

F = acceleration force (N)

m = mass of car (kg)

Example - Acceleration of Sports Car

A sports-car with mass 1000 kg accelerates with acceleration 5 m/s2.  The force required for the acceleration can be calculated

F = (1000 kg) (5 m/s2)

   = 5000 N

   = 5 kN

Acceleration Work

The acceleration work can be calculated as

W = F l                                    (4)

where 

W = work done (Nm, J)

l = distance moved (m)

Acceleration Power 

The acceleration power can be calculated as

P = W / dt                                  (5)

where 

P = power (J/s, W)
