A group of my colleagues at Harvard Health Publishing worked with nutrition experts at the Harvard School of Public Health to create a better version. We call it the Healthy Eating Plate.
Mechanical energy is the energy which is possessed by an object due to its motion or its stored energy of position. Mechanical energy can be either kinetic energy (energy of motion) or potential energy (stored energy of position).
General Background. Mechanical energy exists as both kinetic and potential energy in a system. Kinetic energy is present whenever an object is in motion. Potential energy is based on the position of an object; it is stored energy, and cannot do work on its own.eneral Background.
