Mechanics: Understand Kinetic Energy

a)  Electrical Energy

• Electrical energy is the energy created by the moving of an electron(e^–) through a solid (wire).
  Audio speakers, Lighting, Doorbells,
  Static electricity, Headphones, Batteries in use

b)  Radiant Energy

• Radiant Energy is electromagnetic energy: Learn more about Solar energy…
  Radio waves, Solar Energy (the sun), X-rays, Visible light, Car head-light.

c)  Thermal Energy

• Thermal energy is the energy that used heat to generate electricity.
  A cup of Coffee, Solar Energy (the sun), Boiling water, Oven heat.

c)  Mechanical Energy

• Mechanical energy is the sum of the kinetic and potential energy due to the body in motion.
   Tennis ball moving, A truck moving on the road, A jet flying, A cat running, A moon rotating around.

c)  Sound Energy

• Sound energy is the energy that is produced when an object vibrates and is measured in decibels (dB).
  A guitar sound, A vibrating drum.
