Tuesday May 21 Overview Energy Motion Object Potential Mechanical Energy Chemical Elastic Chemical Gravitational Elastic Gravitational The nature of energy Energy of a spinning bicycle wheel Energy stored in food Work, Power & Energy Work Work is the product of force and distance For a force to do work on an object, some of the force must act in the same direction as the object moves. If there is no movement, no work is done. How do you measure mechanical efficiency? Energy, Work and Mechanical Efficiency Mechanical Efficiency Mechanical efficiency is a comparison of the useful work or energy that a mechanical system produces to the work or energy that was put into the system. LO:. . We will understand that energy can take many forms but the total energy in a system is constant.. . CT: . I . will investigate and calculate the changes of different forms of energy.. .
