Energy: Law of Conservation

January 30, 0215

Do you have difficulty with energy? Below is a video of a VERY COMMON EXAM QUESTION. Learn it well!

Energy Video Learning points:

  1. Energy cannot be destroyed
  2. Energy can only be converted (to a different form) or transferred (from one thing to another thing that possessed the same form of energy)
    Energy Conversion
  3. Kinetic energy is affected by speed and mass
    The faster the object travels, the more kinetic energy it has
    The heavier the object travels, the more kinetic energy it has
  4. Gravitational potential energy is affected by height and mass
    The higher the object is, the more gravitational potential energy it has
    The heavier the object is, the more gravitational potential energy it has
  5. Kinetic energy is usually the opposite of gravitational potential energy.
