is being released as heat and light. As a comet approaches a planet or star, it slows, momentarily affected by the larger body's gravity. The potential energy builds up and then reaches a breaking point as the comet accelerates around the larger body, and is shot out to the other side....

Potential energy is the energy,chemical or physical,stored within an object,atom or molecule(分子).Think about a car at the top of a roller-coaster (过山车),pausing just before it slopes into the next turn.A log resting in a fireplace just before it is about to be lit is a treasure ...
依据在第一小节第一句话中: Potential energy is the energy,chemical or physical,stored within an object, atom or molecule(分子),译为:势能是一种以物理或者化学的形式储存在物体原子或者分子内部的能量。72. releasing (词性转换)。依据在第一小节中 : As the log burns, the connections betweencarbon ...
场强为零,电势不一定为零,因为电势是个相对量 The electric potential is, with the gravitational potential energy which relative says is same, does not have the frame of reference has no way to say its potential energy is how many. Likewise does not select a zero potential spot, is does not ...
The potential energy change is equal to the mechanical work made against the plate weight, therefore the efficiency of the energy transformation is相关知识点: 试题来源: 解析 0.6 Computation of the change in potential energy 0.2+0.2 Correct results for efficiency...
electric potential n. The work per unit of charge required to move a charge from a reference point to a specified point, measured in joules per coulomb or volts. The static electric field is the negative of the gradient of the electric potential. ...
What is the potential energy of a 62 kg person in a skyscraper if he is 462 m above the street?Gravitational Potential Energy:A person falling from a certain height will speed up increasingly according to the Earth's gravitational acceleration. As the person's velocity...
