Energy exists in various forms. The adjective kinetic has its roots in the Greek word κίνησις kinesis, meaning "motion".The dichotomy between kinetic energy and potential energy can be traced back to Aristotle's concepts of actuality and potentiality.. The average kinetic energy of a particle in one period. Rigid bodies which rotate along their center of mass possess rotational kinetic energy. Therefore, the difference between these two types of energy comes down to whether an object i… Draw a chalk line on the floor and have pairs of students stand arms’ length apart with their toes on the line. Objects can have stored, or potential, energy when work has been done (such as raising an object in the air) or by virtue of their position (such as sitting at the top of a hill). When she is not writing, she loves watching sci-fi movies on Netflix. There are two major types of mechanical energy. 8. Given descriptions, illustrations, or scenarios, students will compare and contrast potential and kinetic energy. While kinetic energy is the energy which an object contains because of a particular motion. PE is the energy possessed by an object by virtue of its position. Although kinetic energy and potential energy are both types of mechanical energy, many differences exist between them. In conclusion, all objects possess one form of mechanical energy or the other by virtue of rest or position. This force is called restoring force and acts to bring objects and systems to their low energy level position. However, it must be noted that there is usually a rapid conversion of energy from potential to kinetic when an object which originally possessed potential energy is set in motion, which consequently causes a change in position of the object.
