Document Summary
Power is the rate at which energy is being converted from one form to another, or transferred from one place to another. Four types of basic levels of energy forms: Kinetic forms-any moving object; equal to half the mass of the object times the square of its velocity (ke= mv^2) The ke within a material determines its temperature. Gravitational-object lifted above your head-the input energy is stored in a form called gravitational potential energy. Potential energy=force x distance=weight x height=m g h. Electrical energy: holds together the atoms and molecules of all materials. Chemical energy-form of electrical energy at the atomic level due to when atoms bond with other atoms to form molecules, changing the distribution of electrons. Electrical currents-organized flows of electrons in a material, usually a metal. Electromagnetic energy is radiated in varying amounts by every objects; travels as a wave that can carry energy through empty space. The length of the wave characterizes its form, which.
