The building is kept upright using a system of ballastsaided by a set of squid-like tentacles that generate kinetic energy.

Kinetic energy can be destroyed, but momentum cannot be destroyed in the absence of a net external force on the system as a whole.

动能可以被毁，但是动量不能，在整个系统外力，不存在情况下。

As a result, the generating action of the induction machine will cause the power flow to reverse and the kinetic energy of the drive system will be fed back to the supply.

结果，由于感应电动机为发电机，功率流将反向，拖动系统的动能将被反馈回电网。

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.

Slick, untreaded tyres will also be reintroduced after 11 years on grooved tyres and teams have the option of employing a kinetic energy recovery system.
