http://en.wikipedia.org/wiki/Formula_One_car 沒辦法 現在都是微基老師的天下 大概是我看的意思搞錯 F-1高速踩煞車時是 -4G(?) 放油門就有-1G 不過可能是因為氣動力...XD Deceleration The deceleration force under braking is usually 4 g (39 m/s2), and can be as high as 5–6 g when braking from extreme speeds.... Here the aerodynamic drag actually helps, and can contribute as much as 1.0 g of braking force, which is the equivalent of the brakes on most road sports cars. In other words, if the throttle is let go, the F1 car will slow down under drag at the same rate as most sports cars do with braking, at least at speeds above 150 km/h (93 mph). The drivers do not utilise engine or compression braking, although it may seem this way. The only reason they change down gears prior to entering the corner is to be in the correct gear for maximum acceleration on the exit of the corner...
