Forms of Energy Energy • Energy- The ability to do work • Work- A transfer of energy • Work and energy are measured in joules • Joules- SI unit of work and energy equal to 1 Newton per meter • Newton- SI unit of force Potential Vs Kinetic Energy • Potential Energy- Energy that is stored as a result of position or shape • The higher up an object is, the greater potential energy. • Kinetic Energy- The energy of motion • The greater the speed and mass of the object the greater the kinetic energy Types of Potential Energy • Gravitational Potential Energy-Potential energy that depends upon an object’s height • Elastic Potential Energy- The potential energy of an object that is stretched or compressed. Major Forms of Energy Thermal Energy- (Heat Energy) Total kinetic energy contained in all the particles of a substance. Mechanical Energy- Energy an object has because of its motion or position. Chemical Energy- The energy stored in chemical bonds. Electrical Energy- The energy associated with electrical charges. Light Energy- The energy carried by light and other forms of electromagnetic waves Sound Energy- The energy carried by sound waves Nuclear Energy- The energy stored in atomic nuclei
