Energy is a fundamental concept in physics, representing the capacity to do work. Work, in physics, means applying a force over a distance. There are many forms of energy, but we'll focus on the most common ones you'll encounter.

Mechanical energy ($E_{mech}$) is simply the sum of an object's kinetic energy ($E_k$) and its potential energy ($E_p$). So, $E_{mech} = E_k + E_p$.
