Energy Note Outline Energy is the ability to perform work Units for energy is Joules (J)--kgm²/s²
Energy Note Outline • Mechanical Energy • The sum of the both potential and kinetic energy of a system
Energy Note Outline • Kinetic Energy • Energy that is cause by movement
Energy Note Outline • Gravitational potential energy • Energy caused by the height of an object
Energy Note Outline • Elastic Potential Energy • Energy stored by compression or tension
Energy Note Outline • Dissipated Energy • Thermal energy generated by friction or heat transfer
Energy Note Outline • Formula for kinetic energy (KE) • KE=½mv² • m is mass (kilograms) • v is velocity (m/s)
Energy Note Outline • Formula for Gravitational Potential Energy (GPE) • PE=mgh • m is mass—always kilograms • g is acceleration due to gravity (10m/s²) • h is height of object ( always meters)
