|
Energy |
The ability to do work. |
|
|
Potential Energy |
Stored energy due to position can be converted to kinetic energy when something acts to release it. |
|
|
Gravitational Potential Energy |
Energy an object possesses because of its position in a gravitational field. |
|
|
Elastic Potential Energy |
Potential energy stored as a result of deformation of an elastic object, such as the stretching of a spring. |
|
|
Kinetic Energy |
Energy in the form of motion depends on the mass and velocity of an object. |
|
|
Mechanical Energy |
The energy of an object or system due to its motion or position. |
|
|
Sound Energy |
The movement of energy through substances in longitudinal (compression/rarefaction) waves. Sound is produced when a force causes an object or substance to vibrate — the energy is transferred through the substance in a wave. |
|
|
Radiant ( Light ) Energy |
Energy that travels by waves or particles, particularly electromagnetic radiation such as heat or x-rays |
|
|
Nuclear Energy |
The stored potential energy in the nucleus of an atom, the energy released during nuclear fission or fusion, especially when used to generate electricity. |
|
|
Nucleus |
The center of a cell that controls it consisting of protons and neutrons |
|
|
Atom |
The basic unit of a chemical element. |
|
|
Thermal ( Heat ) Energy |
kinetic energy, as it is due to the motion of particles, with motion being the key. |
|
|
Electricity ( Eletrical Energy ) |
The kinetic energy of moving electrons, negatively charged partials. |
|
|
Electron |
a stable subatomic particle with a charge of negative electricity, found in all atoms and acting as the primary carrier of electricity in solids. |
|
|
Transformations of Energy |
The process of changing one form of energy to another form of energy. |
|
|
Law of Conservation of Energy |
The total energy of an isolated system remains constant—it is said to be conserved over time. Energy can neither be created nor destroyed; rather, it transforms from one form to another. |
