Potential Energy |
Energy stored in an object due to its position. |
|
|
|
Kinetic Energy. |
Energy exerted through a moving object. |
|
|
|
Energy Transformation. |
When energy transforms from one form to another. |
|
|
|
Law of Conservation of Energy. |
Constant energy in an object that can't be created or destroyed. Can can be transferred or transformed. |
|
|
|
Force and Formula. |
F = w/d = N. The application of work done on an object through a distance. |
|
|
|
Friction. |
The resistance between moving objects. |
|
|

|
|
|
Newton. |
(N) A unit of Force. |
|
|
|
Work and Formula. |
w = F • d or w = P • t = J The ability to apply force on an object through a distance. |
|
|
|
Joule. |
(J) Unit of Work. |

|
|
Machine. |
A device having several parts that use mechanical power to do a task. |
|
|
|
Mechanical Advantage and Formula. |
MA = Load Force/Effort Force. The ratio of input and output applies to a machine. |
|
|
|
Efficiency and Formula. |
Eff = Load Force • Load Distance/ Effort Force • Effort Distance. Or Eff = Work Output/ Work Input.
The ratio of useful work done by a machine or process. |
2 possible formulas. |
|
|
Power and Formula. |
P = w/t. The rate of energy being absorbed or transferred. |
