Quick explanation

Recall and apply the formula for the change in gravitational potential energy, expressed as ΔE_p = mgΔh

  • This point belongs to Energy, work and power, especially Energy, work and power outcomes.
  • You need to be able to recall and apply the formula for the change in gravitational potential energy, expressed as ΔE_p = mgΔh.
  • The key ideas to know are Calculate and Define.
  • Use the linked flashcards and practice questions to check recall, then practise applying the idea in an exam-style answer.
