Types Of Energy

6 Different Kinds

Sound Energy

  • Sound waves are made through the transmitted vibration of atoms in bulk
  • Solids, liquids, and gas are transmitted as sound
  • Sound could not travel through a vacuum has no atoms to transmit the vibration

Electrical Energy

  • Electrical energy is carried by moving electrons in a electric conductor
  • All mater consists of atoms and every atom contains one or more electrons which are always moving
  • electricity is one of our most useful forms of energy because its relatively easy transmit and use


  • The friction between two surfaces is considered kinetic energy
  • This property can have a very dramatic consequence
  • Friction is not itself a fundamental force

Thermal Energy

  • thermal energy is the energy a substance or system has related to its temperature
  • Thermal is not the same as heat
  • the amount of heat transferred by a substance depends on the speed and number of atoms

Mechanical Energy

  • Mechanical energy is the most familiar form of energy
  • machines use mechanical energy to do work
  • Our bodies use mechanical energy to perform motions such as throwing a ball

Kinetic and Potential Energy

  • moving a object is a form of kinetic energy
  • it is defined as the work needed to accelerate a body given mass from the rest to its stated velocity
  • of an object is the energy which possess due to its motion
