Energy conservation is the practice of reducing the use of energy. Individual consumers can do numerous things to conserve energy and reduce home energy...

Kinetic energy and potential energy are together referred to as mechanical energy. The total mechanical energy (U) of an object is then the sum of its...

earlier, energy is the capacity to do work. When positive work is done on an object, the system doing the work loses energy. In fact, the energy lost by...

The energy is the ability to do a work. Energy is measured by the result of applied force/power over a period of time to make changes/work. Work is defined...

Similarly, Potential energy is stored energy (people who like to save their jeules) and Kinetic Energy is energy being used. Energy, when it is tranferred...

internal energy. Internal energy is defined as: The internal energy of a system is the sum of the randomly distributed kinetic and potential energies of its...

like matter, energy is something that we are all familiar with and use on a daily basis. Before you go on a long hike, you eat an energy bar; every month...

Nuclei can produce energy via two different types of reactions, namely, fission and fusion reactions. Fission is a break up of a nucleus in two or more...

The sun may appear to be Earth’s only source of energy, but there are other much deeper sources of energy hidden inside Earth. In the pursuit of natural...
