potencial energy

The energy of a body is a measure of the body's ability to conduct a business. Unit of energy is the joule. In the physical sciences are divided into various kinds of energy / types, among others:

- Potential energy
- Kinetic energy / kinetic
- Thermal energy
- Water energy
- Coal energy
- Petroleum energy
- Electricity
- Solar energy
- Wind energy
- Chemical energy
- Nuclear energy
- Natural gas energy
- Wave energy and wave
- Petroleum energy
- Mechanical energy / mechanical
- Light energy
- Electricity
- And others

A. The potential energy or Silent Energy
Potential energy is energy that a body due to the influence of the place or position of the object. The potential energy is also called the rest energy for stationary objects in keaadaan can have energy. If the object is moving, then it changes the potential energy into motion energy. Examples such as coconuts are ready to fall from the tree, lizard in the ceiling of the house, and so forth.

Formula or potential energy equation:
Ep = m.g.h

information
Ep = potential energy
m = mass of the object
g = acceleration due to gravity
h = height of ground objects

B. Kinetic or Kinetic Energy
Kinetic energy is the energy of an object that is owned by the influence of the movement. Moving object has kinetic energy.

Formula or kinetic energy equation:
Ek = 1/2.m.v ^ 2

information
Ep = kinetic energy
m = mass of the object
v = velocity of the object
v ^ 2 = v power of 2

C. Law of Conservation of Energy
"Energy can neither be created nor be destroyed"
So the change in the form of an energy from one form to another form that does not change the amount of energy or as a whole.

Mechanical formula or equation (relating to the law of conservation of energy):
Em = Ep + Ek

information
Mechanical energy Em =
Ep = kinetic energy
Ek = kinetic energy

Note:
Enerti unit is joule
