PHYSICS12ENERGY There are manyforms of energy. In this course we will concern ourselves with mechanicalenergy. Mechanical energy is the energy an objecthas due to its position, or because of its motion. The twotypes of mechanical energy are potentialenergy and kinetic energy. Potential Energy Pot...
