kinetic energy

Internal Energy - Internal energy is one of the most important concepts in thermodynamics. Energy changes in a body sliding with friction. Warming a body increases its internal energy and cooling the body decreases its internal energy. However, what..

Energy in SHM - To cause a displacement of a body controlled by elastic forces, work has to be done. For example, work has to be done in stretching a spring against the elastic forces. This work will be stored in the body as potential energy. When the deforming force is released..

Every substance possesses a definite quantity of energy, under a given set of factors such as chemical nature of the substance, temperature and pressure. The total energy contained in a system or substance is called its internal energy or intrinsic energy. I..

Conversion of gravitational potential energy to kinetic energy: When a body falls from a certain height, its kinetic energy increase..

Energy from the oceans is also available in the form of oceanic waves or sea-waves. Due to the blowing of wind on the surface of ocean, very fast sea-waves (or water waves) move on its surface. Due to their high speed, sea-waves have a lot of kinetic energy in them. T..

Law of Conservation of Energy - Let us see what is actually taking place in the following examples: Steam engine: The coal burns. Heat due to the combustion of coal converts water into steam. The expansive force exerted by the steam on the piston of the engine moves the locomotive. Chemic..

The huge moving waves possess kinetic energy. This energy is used to power a turbine. Most wave-energy systems are very small. But, they can be used to power a warning buoy or a small light hous..

We come across in our day-to-day life different forms of energy, like the mechanical energy, heat energy, electrical energy, chemical energy etc. Here in this chapter, we are mainly concerned with mechanical energy. The two types of mechan..

Energy can manifest itself in a number of forms. We have already seen that it can be in the form of mechanical energy, which is subdivided into kinetic energy and potential energy. Potential energy can arise due to different causes. For in..

Illustration of Conservation of Mechanical Energy - Conversion of gravitational potential energy to kinetic energy: When a body falls from a certain height, its kinetic energy increase..
