Unit 4: Work, energy and power (Hindi)

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.
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.
