Topics in Energy

1

1. Work, Energy, and Units

  • Work is done only when a force moves a body in the direction of the force.
  • If no motion takes place, no work is done.
  • Energy is the capacity to do work.
2

2. Forms of Energy

  • Energy exists in several forms: mechanical, heat, light, chemical, sound, magnetic, electrical, and atomic energy.
  • Mechanical energy is the energy possessed by a body due to its state of rest or motion.
  • Heat energy is energy released when fuels such as coal, oil, wood, or gas burn.
3

3. Mechanical Energy: Potential and Kinetic

  • Mechanical energy is the sum of potential energy and kinetic energy.
  • Potential energy is the energy possessed by a body due to its state of rest or position.
  • Kinetic energy is the energy possessed by a body due to its state of motion.
4

4. Conversion of Energy

  • Energy can change from one form to another.
  • In a steam engine, chemical energy of coal changes into heat energy of steam and then into mechanical energy.
  • In an electric motor or fan, electrical energy changes into mechanical energy.
