The video tutorial introduces mechanical energy, explaining it as the energy of motion or stored energy. It distinguishes between kinetic energy, which is energy in motion, and potential energy, which is stored energy. Through various examples, such as a skier, a balloon, a bow and arrow, and a roller coaster, the video illustrates how these energy types manifest in real-world scenarios. The tutorial concludes by summarizing the key concepts of mechanical energy, emphasizing its two components: kinetic and potential energy.

What is mechanical energy?
