Car  Traction Force
Adhesion and tractive force between car wheel and surface.
The tractive force between a car wheel and the surface can be expressed as
F = μ_{t} W
= μ_{t} m a_{g} (1)
where
F = traction effort or force acting on the wheel from the surface (N, lb_{f})
μ_{t }= traction  or friction  coefficient between the wheel and the surface
W = weight or vertical force between wheel and surface (N, lb_{f}))
m = mass on the wheel (kg, slugs)
a_{g} = acceleration of gravity (9.81 m/s^{2}, 32.17405 ft/s^{2})

Example  Traction Force on an Accelerating Car
The maximum traction force available from one of the two rear wheels on a rear wheel driven car  with mass 2000 kg equally distributed on all four wheels  on wet asphalt with adhesion coefficient 0.5  can be calculated as
F_{one_wheel} = 0.5 ((2000 kg) (9.81 m/s^{2}) / 4)
= 2453 N
The traction force from both rear wheels
F_{both_wheels} = 2 (2452 N)
= 4905 N
Note!  that during acceleration the force from the engine creates a moment that tries to rotate the vehicle around the driven wheels. For a rear drive car this is beneficial by increased vertical force and increased traction on the driven wheels. For a front wheel driven car the traction force will be reduced during acceleration.
The maximum acceleration of the car under these conditions can be calculated with Newton's Second Law as
a_{car} = F / m
= (4904 N) / (2000 kg)
= 2.45 m/s^{2}
= (2.45 m/s^{2}) / (9.81 m/s^{2})
= 0.25 g
where
a_{car} = acceleration of car (m/s^{2})
The minimum time to accelerate from 0 km/h to 100 km/h can be calculated as
dt = dv / a_{car}
= ((100 km/h)  (0 km/h)) (1000 m/km) (1/3600 h/s) / (2.4 m/s^{2})
= 11.3 s
where
dt = time used (s)
dv = change in velocity (m/s)
