Lesson: Power and Energy Physics

In this lesson, we will learn how to use the formula P = E/t to calculate the rate at which energy is transferred by a device given the amount of energy it transfers in a given time.

Lesson Plan

Students will be able to

  • give a definition of power in terms of energy and time,
  • use 𝑃=𝐸𝑡 in all permutations,
  • apply 𝑃=𝐸𝑡 to electric circuits and appliances.
