Kinetic Energy: Energy that a body has as a result of its motion. Mathematically, it is defined as one-half the product of a body's mass and the square of its speed.
Light Energy: Light is a type of energy (and the tiny part of the electromagnetic spectrum that we can see). The fastest that light can travel is 186,300 miles per second. Visible light has a wavelength from 10 -7 m to 10 -8 m. LIGHT SPECTRUM Light can be broken up into into its component colors (for example, by passing light through a prism) - this is a spectrum. Light from the Sun can be broken up into the colors of the rainbow (red, orange, yellow, green, blue, indigo, and violet).
Potential Energy: The energy stored in a raised object (eg the weights in a grandfather clock). Potential energy equals mgh, where m is mass, g is the acceleration of gravity, and h is the vertical distance from a reference location. It is called potential energy because the energy can be regained when the object is lowered. This type of potential energy is sometimes called gravitational potential energy in order to distinguish it from elastic potential energy: see elastic energy.
Chemical Energy: Potential energy stored in chemical bonds of molecules.
Gravitational Potential Energy: A type of potential energy. Gravitational potential energy is associated in the interaction of an object with the earth. It is defined to be equal to the mass of the object times the gravitational acceleration times the distance of the object from the ground.
