Kinetic and potential energies

OCR A AS Physics · 3.3.2

Explore kinetic and potential energies within work, energy and power. Follow energy transfers through a system. Work connects a force acting through a displacement to an energy change, and power measures how quickly energy transfers.

Specification outcomes (3)
  • 3.3.2(a) Define and calculate kinetic energy, Ek = ½mv², and derive it from first principles.
  • 3.3.2(b) Define and calculate gravitational potential energy, Ep = mgh, and derive it from first principles.
  • 3.3.2(c) Explain the exchange between gravitational potential energy and kinetic energy.
