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).
A drawn bow possesses mechanical energy due to its stretched position (elastic potential energy). An object which possesses mechanical energy is able to do work. In fact, mechanical energy is often defined as the ability to do work. Any object which possesses mechanical energy-whether it be in the form of potential energy or kinetic energy-is able to do work. That is, its mechanical energy enables that object to apply a force to another object in order to cause it to be displaced.
