We use energy to do work, energy is defined as the ability to do work. A system that possesses energy has the capability to do work on another. Energy is expressed in joules or ergs. Energy, like work, is also a scalar quantity. There are many forms of energy: mechanical, heat, light, and chemical energy. In this SLeM, we will focus on mechanical energy. The sum of potential energy and kinetic energy is called mechanical energy. We will also discuss work in relation to potential energy #potentialenergy #gravitationalpotentialenergy #work #newton'slawofmotion #workandenergy https://drive.google.com/file/d/1hbmENZPDgPJCcUgULSffplj022GYA7kl/view?usp=sharing
