现代的F1赛车上都有大量的传感器，传感器记录了海量的关键数据，像是油门、制动、加速度等等，并将这些数据传送到后方。

Modern F1 cars are fitted with hundreds of sensors that amass data on key parameters, such as throttle, braking and acceleration, and then send them back to the pits.

在这一点上，提供了油门的立场是持续的，汽车会保持设定的速度。

At this point, provided the throttle position is sustained, the vehicle will maintain the set speed.

If it's going in a circle, you will say from now on, that it, indeed, has an acceleration, even though no one's stepping on the accelerator, of amount v^2 over R.

如果它在一个圆周上运动,你会说从现在起它其实有加速度,即使没有人去踩油门,加速度大小为 v^2 / R
