Could you tell me the answer?
what are the differences between the words "power" and "energy"???
For example,"To regain their ( ) after an exhausting game ,the players lay in the grass." the answer is 'energy ' Why ?why can't I fill in the "power'?
最佳答案
"Power" and "energy" are almost synonymous.
Strictly speaking power is an abstract term meaning authority: "the power of government to rule", "people power", "police powers". It can also mean "strength"
Energy is a more precise, scientific term.
An athelete needs energy to run a race but not power.
He digests food to extract energy which is converted into strength in his legs.
Electical power, steam power, wind power, are different types of energy, and in these cases the correct term would be "energy", though "power" is acceptable in popular usage.
In an automobile the potenial energy in the petrol is converted into power to accelerate.
"Power" is the strength to do something extracted from "Energy".
Power用在人身上的时候是指精神力量，或者权利。Energy是指物理能量，也有动力的意思。所以在例句里，运动员所需要补充的是物理能量，应用energy。
power指的是能源（电力、风能、石油。。。。）：而enery指的是生理方面的能量（核糖核肝酸。。。。）
energe指人的精力和物理学上的能；power指动力、权力。就上面的问题来看，肯定要选energe了---
Excellent!
