Is there a scientific formula inorder to know how to make a car drift? like mass,velocity,force etc.?Author: Mike Daniels // Category: Formula Drift
How 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 .
