Potential energy is defined as the work which we have to do on the system to bring it into a certain configuration at rest from another configuration at rest in which it has zero potential energy ie in which there are no forces acting If you think in terms of this definition you will know which sign to use, and what the sign means Internal Energy The internal energy of a system is identified with the random, disordered motion of molecules;Physics of Energy II 8 We can check that potential energy indeed has the units of energy É PE =mgh If the mass is measured in kilograms and the height in meters then the units of potential energy work out to be É kg!(ms"2)!m=kg!m2!s"2=Joules Finally, back to gravitational potential energy Recall these units came out naturally from

Eg of electric potential energy
Eg of electric potential energy-In Physics, potential energy (PE) is said to be equal to a product of mass (m) in Kilograms, Acceleration due to gravity (g) in m/s 2 and height (h) in meters ThatThe change in gravitational potential energy (ΔPEg) between points A and B is independent of the path The equation ΔPE g = mgh applies for any path that has a change in height of h, not just when the mass is lifted straight up (See Figure 2) It is much easier to calculate mgh (a simple multiplication) than it is to calculate the work done

Thus, the work is the same in path 1 and 2 Potential energy is the latent energy in an object at rest, and is one of two forms of energy The other form, kinetic energy, is the energy expressed by an object in motionPotential energyF in the definition of potential energy is the force exerted by the force field, eg, gravity, spring force, etc The potential energy U is equal to the work you must do against that force to move an object from the U=0 reference point to the position r
When a conservative force does negative work, the system gains potential energy When a conservative force does positive work, the system loses potential energy, ΔU = −W In the system in Figure 73, the Coulomb force acts in the opposite direction to the displacement;Gravitational potential energy is the energy stored in an object as the result of its vertical position or height The energy is stored as the result of the gravitational attraction of the Earth for the objectGravitational potential energy is a type of energy an object has due to it being raised above the ground The amount of gravitational potential energy the object has as it is lifted can be determined by measuring the amount of work it took to get the object there using the height it was raised (h), its mass (m) and the gravitational pull of the earth (g), which is 10 N/kg
Potential energy is the energy associated with position, like a ball held up in the air When you let go of that ball and let it fall, the potential energy converts into kinetic energy, or the energy associated with motion There are five types of kinetic energy radiant, thermal, sound, electrical and mechanical Let's explore several kineticWhat is it on the moon (g = 16 m/s2)?Examples of Potential Energy 1 A rock sitting at the edge of a cliff has potential energy If the rock falls, the potential energy will be converted 2 Tree branches high up in a tree have potential energy because they can fall to the ground 3 A stick of dynamite has chemical potential energy

The amount of potential energy that an object possesses depends on the object's mass or weight, its height above the surface, and the strength of the gravitational field If the other factors are the same, a heavy object will have more gravitational potential energy than a lighter object An object 1 mile (16 km) up in the sky will have moreThe gravitational potential energy of an object is the 'stored energy' that the object has by being at that height This is equivalent to its mass times the force of gravity, g (a defined constant of 98 m/s 2) times the height of the object Potential energy = mass x gravity x height Egrav = PE = mgh The relationship between gravitational potential energy and the mass and height of an object is described by the following equation PE grav = m * h * g Where
