重力位能 meaning in English
gravitational potential energy
Examples
- On the way down , the ball gains kinetic energy at the expense of gravitational energy
球往下掉时，重力位能又转换回动能。 - They move around and change speed as their balance of gravitational and kinetic energy shifts
它们运动的速度会因重力位能与动能的消长而改变。 - Bodies traveling in a gravitational field are always undergoing an exchange of gravitational and kinetic energy
在重力场中运动的物体会不停地改变其动能与重力位能。 - Early on , dense iron sank out of the magma oceans to form the metallic core , liberating enough gravitational energy to melt the entire planet
更早期的时候，较重的铁自岩浆海中析出下沉，渐渐形成了金属成份的地核，下沉时释放出的重力位能足以把整个地球再次熔融。
