|
gravitational potential energy |
energy due to an objects height |
|
|
kinetic energy |
type of mechanical energy; energy of motion |
|
|
work done on an object |
this must be parallel or at an angle for this value to be non-zero. If the force and displacement are at right angles to one another, no___ is done! |
|
|
work done by friction |
slows the object down; negative work |
|
|
joule |
SI unit of energy |
