Virtually all forms and types of energy are useful in some way or another.
The energy that is not useful is called waste energy. It is the energy that is not harnessed or converted into a form that can be utilized for work or other useful purposes.
A body with mass in motion possesses kinetic energy. If it is subject to friction, either on a rough surface or through the air, some of this energy will be converted to thermal energy, ie it will heat up. An extreme example of this is the re-entry of space vehicles into the atmosphere. It could also be converted to potential energy, such as when you fire a bullet upwards, it eventually stops rising, partly because of friction but also because it is being pulled back by gravity.
That may refer to the system's efficiency (which is formally the amount of useful output power divided by the amount of input power).
Energy efficiency is typically determined by the ratio of useful energy output to total energy input in a system. It can be quantified by calculating the efficiency percentage, which is the amount of useful energy produced divided by the total energy input multiplied by 100. The higher the percentage, the more energy efficient a system is.
Efficiency is the ratio of useful energy output to total energy input. A higher efficiency indicates that a greater proportion of the total energy input is being converted into useful energy output. Therefore, as efficiency increases, the amount of useful energy output relative to total energy output also increases.
Useful Energy
Yo, no energy is unuseful at all we need all of them to surive and to live.
Torque and horsepower.
Nuclear Energy produces radioactive waste because if there isnt any sign of nuclear waste/energy in the sullotion/object then it wouldnt be counted as 'Radioactive'.
isnt it a fry pan? if it is it helps us cook.
there isnt really any use
no it isnt
Nacho cheese.
