Energy may be stored (potential energy), or it can be said to be a property of an objects motion (kinetic energy). While the scientific definition of energy has been refined for centuries and thus has a very specific meaning, the mainstream usage of the word is often in conflict with ...
Energy is the capacity to do work. Energy appears in many forms. Fossil fuels, such as coal, oil, or gas, contain energy in the form of chemical energy. Burning releases the stored energy in the form of heat energy. Nuclear energy is contained in the form of bonding forces within the ...
Learn about energy and discover the different types of energy. Explore potential energy, kinetic energy, and how energy is simply the ability to do...

What is the scientific definition for the word "Electricity?" We'd expect that physicists have a clear definition for "the quantity of electricity." However, it might suprise you to learn that the following sources are unanimous in saying that Electricity isnota form of energy. Instead, they...
The energy source in the science fiction world is running out. What is the most likely solution? A. Find a new energy source. B. Continue using the old source. C. Give up on energy. D. Do nothing. 相关知识点: 试题来源: 解析 A。解析:当能源耗尽时,最可能的解决方案是寻找新的能源...
(16年真题) A. what B. that C. whether D. if 相关知识点: 试题来源: 解析 答案B 解析 本题考察了定语从句,本题原意为“能量既不能被创 造也不能被消灭,这是一个科学准则” ,先行词是law in science,后面的energy cannot be created or destoryed对先行词进行限定,所以选B。 反馈 收藏 ...

In an ideal gas, internal energy is proportional to the number of particles of moles of a gas and its temperature: U = cnT Here, U is internal energy, c is the heat capacity at constant volume, n is the number of moles, and T is the temperature. ...
The joule (symbol: J) is the basicSI unitofenergy. A joule is equal to thekinetic energyof a kilogrammassmovingat the speedof one meter per second (one joule is a kg⋅m2⋅s−2). Alternatively, it is the amount of work done on an object when a force of onenewtonacts in the...
