Potential Energy

  • Object lifted above the ground gains potential energy (PE)
  • Often called GPE
  • Additional height gives it the potential to do work when it falls
  • A diver on a diving board has GPE
  • Potential energy (J)= Mass (Kg)x Acceleration of free fall (N/kg)change in height (h)
  • G acceleraton of free fall because gravity is involved
  • Acceleration of free fall also referred to as g which can assume is constant and has a value of 10 N/kg
  • Every 1kg of matter near the surface of earh experiences a downards force of 10N due to gravity
