These movements you feel are accelerative forces, and they are acting through the centre of gravity. Equally, you have experienced rolling in corners, and squat - the car sitting down in acceleration if you put your foot down hard enough.
Gravity formula driver#
You know from traveling in a road car that when the driver brakes, the car dives down at the front. If you apply the force in a direction that does not pass through the CoG, it will make the car rotate unless it is balanced by another force.įor a racing car, the CoG is located between the front and rear wheels and as close to the ground as physically possible. It is measured relative to a reference datum using moment balance equations. CoG location is directly a function of the coordinate system in which it is referenced. The center of gravity location must be referenced to a 3 dimensional coordinate system. The center of gravity (CoG) is also called center of mass. The point about which gravity moments are balanced
The point through which a force will cause pure translation
It must be as low as possible to the ground, and this is not only because the weight act through it, but also because all accelerative forces of acceleration, braking and cornering work trough it.Īny force that acts through the CoG has no tendency to make the car rotate.Ĭenter of gravity location can be defined as: The centre of gravity is perhaps the single most critical area of any racing car weight consideration.
