Cars can do more than 1G even without downforce. Sports car street tires commonly ~1.2g, race tires commonly ~1.5g+ High school friction is wrong. Source: va

High school friction is wrong.

- LeifCarrotson 10y ago> High school friction is wrong. No, it's at least mostly correct. High school friction says F = mu * W Where F is the output force, mu is the coefficient of friction, and W is the normal force (typically equal to the weight). If it's failed you, it's failed in failing to mention that the tire-road interface can have a coefficient of friction greater than one, and in failing to mention that the normal force can be increased with aerodynamic downforce.
- jackmott 10y agoHigh school physics tends to claim that the coefficient can't be greater than one. Source: note all the people here who thought it couldn't be greater than one.
- hx87 10y agoHow is that due to high school physics rather than naive intuition?
- Dylan16807 10y agoMine never implied that, and I could have easily disproved it with the grippy pads on my giant calculator.
