Chapter 7 (Energy)

Calorie

A unit of heat and energy equal to the amount of energy requires to raise the temperature of 1 gram of water by 1° Celsius.

chemical energy

Chemical energy is the potential of a chemical substance to undergo a transformation through a chemical reaction to transform other chemical substances

mechanical energy

mechanical energy is the sum of potential energy and kinetic energy. It is the energy associated with the motion and position of an object.

Joule

the SI unit of work or energy, equal to the work done by a force of one newton when its point of application moves one meter in the direction of action of the force, equivalent to one 3600th of a watt-hour.

potential energy

the energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors.

nuclear energy

the energy released during nuclear fission or fusion, especially when used to generate electricity.

Law of Conservation of Energy

the law of conservation of energy states that the total energy of an isolated system remains constant, it is said to be conserved over time. This law means that energy can neither be created nor destroyed;

Energy

Energy, in physics, the capacity for doing work. It may exist in potential, kinetic, thermal, electrical, chemical, nuclear, or other various forms. There are, moreover, heat and work

radiant energy

Radiant energy is energy that travels by waves or particles, particularly electromagnetic radiation such as heat or x-rays.

kinetic energy

energy that a body possesses by virtue of being in motion.
