potential energy?

Question

What do u know about potential energy??

Answer 1

Potential Energy:

Potential energy exists whenever an object which has mass has a position within a force field. The most everyday example of this is the position of objects in the earth's gravitational field.
The potential energy of an object in this case is given by the relation:


PE = mgh

where
PE = Energy (in Joules)
m = mass (in kilograms)
g = gravitational acceleration of the earth (9.8 m/sec2)
h = height above earth's surface (in meters


Potential energy is also known as the work done by a certain force (such as gravitational force or Coulomb force) when the relative positions of objects are changed within a physical system.
Gravitational potential energy is the work of gravitational force (usually taken with negative sign due to path convention).


The gravitational force keeps the planets in orbit about the Sun.For example, consider a book placed on top of a table

Answer 3

Potential energy is the energy connected to the position of a body in a conservative force field.
Some examples are gravity energy, electrical energy, Archimedes energy, VanderWaals energy.

When the force is acting then the potential energy decreases and (because of conservation of energy) increases the same amount.

Answer 4

The energy an object has because of its position, rather than its motion. An object held in a person s hand has potential energy, which turns to kinetic energy — the energy of motion — when the person lets it go, and it drops to the ground.

Answer 5

Potential energy in a gravity field is a function of the gravity power level relative to the gravitating mass.The bigger the mass that intersects the field power level the more energy it uses to move within the field.Gravity power level is also the time potential level of space.

Answer 6

potential energy= mgh
mc^2
(1/2)kx^2 for a spring
GmM/r for planets
Its the opposite of kinetic energy in most cases
Its negative change in work
It has the potential to be energetic

Answer 7

P.E.= mgh

gis gravity
h is height
m is mass
