WebMy interest in mechanical engineering stemmed from when I discovered the sport of Formula 1 racing in 2016 through surfing the web. I was fascinated by the cars flying around the track as fast as ... In physical sciences, mechanical energy is the sum of potential energy and kinetic energy. The principle of conservation of mechanical energy states that if an isolated system is subject only to conservative forces, then the mechanical energy is constant. If an object moves in the opposite direction of a conservative net force, the potential energy will increase; and if the speed (not the velocity) of the object changes, the kinetic energy of the object also changes.
