|
Kinetic energy |
The energy a moving object has because of its motion. |
Kinetic energy (joules)=1/2 mass(kg)•[speed(m/s)]^2
KE=1/2mv^2 |
|
|
Joule |
SI unit of energy. Abbreviated J |
|
|
|
Potential energy |
Stored energy due to position |
|
|
|
Elastic Potential Energy |
Energy stored by something that can stretch or compress |
|
|
|
Chemical Potential Energy |
Energy stored in chemical bonds |
|
|
|
Gravitational Potential Energy (GPE) |
Energy stored by objects due to their position about earths surface |
GPE(J)=mass(kg)•acceleration of gravity(9.8 m/s^2) • height (m)
GPE=mgh |
|
|
Mechanical energy |
The total amount of potential and kinetic energy in a system. |
ME=PE+KE |
|
|
Law of conservation of energy |
States that energy cannot be created or destroyed |
