... According to Newton’s Third Law, the car is driven by the forward frictional push of the ground on tyres. If we apply the brakes (very hard), the wheels are locked and thus prevent from rotating. As a result, the car skids and decelerates. The decelerating force is actually the sliding friction（滑動 摩 ...
