|
|
Newton |
A unit measuring applied force |
|
|
Joule |
a unit measuring work |
|
|
Machine |
Any device that changes the force or increases the motion from work |
|
|
Simple Machine |
A machine that does work with only one movement of the machine |
|
|
Compound Machine |
A combination of two or more simple machines |
|
|
Efficiency |
The ratio of output work to input work |
|
|
Efficiency Equation |
e=W(out)/W(in) X 100 |
|
|
Mechanical Advantage |
The ratio of output force to input force |
|
|
