Kinetic energy |
It is the energy possessed by bodies that are in motion. The bodies acquire kinetics to be accelerated by the action of forces, or when a work is done about them energy. |
|
|
Potential energy |
An object has energy when it is in motion, but may also have potential, which is the energy associated with the energy position of the object |
|
|
Energy |
It is the capacity that has a body for produce work |
|
|
Conservation of the energy |
"Energy is neither created nor destroyed, only transformed" |
|
|
Equation of Kinetic energy |
K= ½ mv2 |
|
|
Equation of potential energy |
U= mgh |
|
|
Equation of elastic energy |
Ur= 1/2 kd2 |
|
|
Equation of work |
W= Fd= Fd Cos angle |
|
|
Principle of conservation energy |
Einitial= Efinal |
|
|
Conservative forces |
If the work done to move the object from point A to point B, is independent of the path that follows between these two points, this means that the value of the work must always be the same even if you use different paths |
|
|
Non-conservative forces |
If the work made to move from point A to point B, is not independent of the path between these two points, this means that the value of the work is different when using different paths |
