Unit: Work, energy and power

You're doing a lot more work than you realize (most of which goes unpaid). This lesson will introduce the definition of work we use in physics, which will give us another way to think about forces and movement.
Kinetic energy is the energy an object has because of its motion. We'll talk about how to calculate kinetic energy, and how kinetic energy is related to work.
Learn what power means and how we use it in physics to describe the rate of energy transfer.

About this unit

"Energy" is a word that's used a lot. Here, you'll learn about how it's one of the most useful concepts in physics. Along the way, we'll talk about work, kinetic energy, potential energy, and conservation of energy.
