Work done is equal to: |
Force * distance |
|
Kinetic energy |
Kinetic energy of a body can be defined as the amount of work it can do in coming to rest. E=1/2 mv² |
|
Derivation of 1/2mv² |
W=Fs W=mas (F=ma) as= v²/2 W=1/2mv² |
|
Potential energy |
The energy a body possesses due to it's position is called it's potential energy. |
|
Gravitational potential energy |
GPE is the amount of work that was done on the object to give it that energy. GPE=mgh |
|
Conservation of energy |
In a system where the only forces acting are associated with potential energy, the sum of kinetic and potential energies is constant. |
