Q

Forms of energy

A
  • Heat (produced by friction, causes a change in temperature)
  • Sound (anything that makes sound)
  • Chemical (atoms are bonded, when they are broken, energy is produced)
  • Electrical
  • Electromagnetic (light, carried by x-rays, radio waves, laser light)
  • Nuclear (when the nucleus is split, nuclear energy is released in the form of heat energy and light energy)
  • Mechanical (energy possessed by an object due to its motion or position)
    • Kinetic Energy (energy of motion)
    • Gravitational Potential (stored energy of position)
    • Elastic Potential (stored energy as a result of applying a force to deform an elastic object)
