Is there a scientific formula inorder to know how to make a car drift? like mass,velocity,force etc.?
Author: Mike Daniels // Category: Formula DriftHow can I apply physics with drifting? Like knowing the acceleration,mass,velocity etc? Is there an existing formula for this? Thank you
In a frictionless environment, the basic formulae are these:
(1) f= m a
f is force, m is mass, a is acceleration. Newton’s second law.
(2) d = 1/2 a t^2
d is distance, t is time: for a body under uniform acceleration
(3) e = 1/2 m v^2
e is (kinetic) energy, v is velocity.
To compute air resistance, you need to know the coefficient of drag (Cd) of the object in question. A flat plate has a Cd of about 1, while an airplane wing might be as low as .001; a car would typically be about .35 . Then drag can be computed as follows:
(4) D = 1/2 ρ A v^2 Cd
where ρ (rho) is the mass density of the air, A is the surface area of the object, v is velocity, and Cd is coefficient of drag.
Friction is described by a coefficient μ that must be determined by experiment. Knowing μ, friction is given by:
F = μ N
where N is the force (in Newtons; see equation 1) pushing the two rubbing objects together. For steel on steel, as in a ball bearing, μ is about 0.4 .

Well the major formula would be that of friction/traction. You need to relate the traction of a cars tires to the different forces being exerted on it (by the velocity and angle of the car). Also playing into this would be the formula for lift and drag, centrifical force, and angular momentum.

better work with friction, static and sliding, rotational velocities also. There must be a formula because the racing games have a drifting mode.
