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.
