Kinetic, potential, thermal, chemical, electrical, electrochemical, electromagnetic and nuclear energy are the different forms of energy. Each energy form measures the ability of an object to do work on another object. Each energy form is a way that an object possesses energy.Know More
Kinetic energy refers to an object or system in motion. For example, a ball flying through the air possesses kinetic energy. Potential energy is an object's potential to turn into kinetic energy. A book sitting on a table has potential energy because it could fall off the table. Thermal energy is related to the temperature of a system. The higher temperature results in an increase in potential and kinetic energy.
Chemical energy is a form of microscopic potential energy. For example, glucose reacting with oxygen releases energy. Electrical energy produces electric currents that can be transferred from one system to another. Electrochemical energy is electric energy that can be stored in a chemical way. A car battery is an example of an electrochemical energy source. Electromagnetic energy is light energy. The sun transmits light to the Earth through radiation. Nuclear energy is a source of energy that involves a change in the structure of the nuclei of atoms.Learn more about Motion & Mechanics
Electrical energy and gravitational potential energy are two examples of stored energy. Energy can be stored or transferred. Energy that moves between or among places is referred to as kinetic energy, while energy that accumulates in single sources is called stored energy or potential energy.Full Answer >
Potential energy is defined as the energy possessed by a body due to its position or height above the surface of the Earth. Water stored in a dam has potential energy. This potential energy has the capacity to do work.Full Answer >
Power is the rate at which work is done, and energy is the capacity for doing work. Energy is often expressed in kilowatt-hours, and power is often expressed in kilowatts.Full Answer >
Some dissipation of energy in the form of heat always accompanies the transformation of energy from one form to another. The transformation of energy is a thermodynamic process, and all such processes are accompanied by a net increase in the entropy of the system through the dissipation of heat.Full Answer >
