Potential energy |
Energy without motion Unit: foot/pound or inch / pound |
|
|
Potential energy can be classified as three groups |
1due to position 2 due to elastic body 3 due to product work through chemical action |
|
|
Potential energy law |

Kinetic energy |
Is the energy in motion Unit: foot/pound or inch / pound |
|
|
Kinetic energy law |
1/2 mass *velocity 2 |
|
|
First law newton |
Object at rest remain at rest Object in motion remain in motion at constant speed unless acted on by unbalanced force |
