The notes outline fundamental physics ideas about *work* and *energy* in a concise, step‑by‑step manner. Energy is introduced as the capacity to do work; it is a scalar quantity whose SI unit is the Joule (J). The discussion then focuses on *kinetic energy (KE)*, which is the energy possessed by a body because of its motion and is always positive. The expression for kinetic energy is given by the well‑known formula $text{KE} = frac{1}{2} mv^2$, where $m$ is mass and $v$ is velocity...
