Physics Energy

Law of Conservation of Energy energy cannot be created or destroyed only transferred from one form to another Electric  LightChemical  Mechanical

2 forms of mechanical energy 1. Kinetic energy (KE) -energy due to motion KE = ½ mv 2 (J) (kg)(m/s) 2 m is the mass of the object in kg v is the velocity in m/s

2. Potential energy (PE) -energy due to position or condition ex: book high on a shelf stretched rubber band wound up clock Known as gravitational potential energy PE = m g h (J) (kg)(m/s 2 )(m) m is the mass of the object in kg g is the acceleration due to gravity 9.81m/s 2 h is the height in m
