Pages 140-145

what is energy
What is Energy?
  • Energy is the ability to do Work or cause a change
    • Measured in Joules, like Work
kinetic energy
Kinetic Energy
  • Kinetic Energy is the energy of motion
  • All moving objects have Kinetic Energy (KE )
  • What determines an object’s KE?
    • Mass & Velocity determine the KE of an object.
potential energy
Potential Energy
  • Potential Energy (PE ) is stored energy
    • It has the potential or “possibility” to do work
  • Gravitational PE is energy that depends on height
  • Elastic PE is for objects that can be stretched.
mechanical energy
Mechanical Energy
  • Energy associated with motion (KE & PE)
thermal energy
Thermal Energy
  • Energy of particles in an object
chemical energy
Chemical Energy
  • Energy stored in chemical bonds
electrical energy
Electrical Energy
  • Moving electric charges
electromagnetic energy
Electromagnetic Energy
  • Waves of energy, such as light
nuclear energy
Nuclear Energy
  • The fusion or fission of atoms
