15.1 Notes - Energy and Its Forms

  1. 1. ENERGY <ul><li>The ability to do work </li></ul><ul><li>When work is done on an object energy is transferred. </li></ul><ul><li>2 types </li></ul><ul><ul><li>Kinetic – moving objects </li></ul></ul><ul><ul><ul><li>KE = ½ mv 2 </li></ul></ul></ul><ul><ul><ul><li>Potential – stored energy </li></ul></ul></ul>
  2. 2. 2 types of Potential <ul><li>Gravitational – depends on objects height </li></ul><ul><li>PE = mgh </li></ul><ul><li>Elastic – potential energy of something that is stretched or compressed </li></ul>
  3. 3. Forms of Energy 15-1
  4. 4. Mechanical Energy <ul><li>Energy associated with motion and position of everyday objects </li></ul><ul><li>It is the sum of potential and kinetic energy </li></ul>
  5. 5. Thermal Energy <ul><li>Total potential and kinetic energy of all microscopic particles in an object </li></ul><ul><li>When particles move faster the thermal energy increases </li></ul>
  6. 6. Chemical Energy <ul><li>Energy stored in the chemical bonds of a compound </li></ul><ul><li>Energy is released when bonds are broken </li></ul>
  7. 7. Electrical Energy <ul><li>Energy associated with electrical charges </li></ul><ul><li>These charges exert forces that do work </li></ul><ul><li>EX batteries and lightening </li></ul>
  8. 8. Electromagnetic Energy <ul><li>Energy that travels through space in waves </li></ul><ul><li>Often used in communications </li></ul>
  9. 9. Nuclear Energy <ul><li>Energy stored in atomic nuclei </li></ul><ul><li>Nuclear Fission releases energy by splitting nuclei </li></ul><ul><li>Nuclear Fussion releases energy when nuclei form a massive nucleus – This is the power of the sun </li></ul><ul><li>Nuclear power plants produce electricity </li></ul><ul><li>Atoms are split and the heat generated is used to heat water </li></ul><ul><li>Steam Spins turbines making electricity </li></ul>
