That means the sum of potential energy and kinetic energy.

总功指的是势能,和动能的总和。

Then we have the conservation - of mechanical energy — the sum of kinetic energy and potential energy.

我们知道，机械能守恒定律-，动能和，势能的总和。

So what, now, is then the total -- energy of the system-- that is, the sum of the kinetic energy plus the potential energy?

所以现在系统内,总能量是多少-,是动能和,势能之和吗？

They include changes to the aerodynamics, the re-introduction of slick, untreaded tyres after 11 years with grooved rubber and the potential use of a kinetic energy recovery system (Kers), which stores energy that would have been dissipated during braking and reapplies it while the car is accelerating.
