Forms of Energy Kinetic Energy: a form of mechanical energy. It has to do with mass in motion. (KE= 1/2mv2) Potential Energy: associated with position in a force field. For gravitational field: PE =w. h Electric Energy: If an electric charge, q, is taken to a higher electric potential (higher voltage),v, then it is capable of releasing its potential energy, given by Pe=g V, in some other form such as heat or mechanical energy Electromagnetic Radiation: takes the form of self-propagation waves in a vacuum or in matter it consists of electric and magnetic components which oscillate in phase perpendicular to each other and perpendicular to the direction of energy propagation. The electromagnetic spectrum covers a very wide range of frequency, and visible light is only a small part of the entire spectrum. The energy per photon can be calculated from the Planck-Einstein equation: E=hvForms of Energy: Kinetic Energy: a form of mechanical energy. It has to do with mass in motion.
