1 Energy Note Outline Energy is the ability to perform work Units for energy is Joules (J)--kgm²/s²

2 Energy Note Outline Mechanical Energy – The sum of the both potential and kinetic energy of a system

3 Energy Note Outline Kinetic Energy – Energy that is cause by movement

4 Energy Note Outline Gravitational potential energy – Energy caused by the height of an object

5 Energy Note Outline Elastic Potential Energy – Energy stored by compression or tension

6 Energy Note Outline Dissipated Energy – Thermal energy generated by friction or heat transfer

7 Energy Note Outline Formula for kinetic energy (KE) – KE=½mv² m is mass (kilograms) v is velocity (m/s)

8 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)
