Definitions
 Potential energy is the energy possessed by a body by virtue of its position or state.
 Potential energy is the energy due to position or configuration, and kinetic energy is the energy due to motion.
 Potential energy is the energy that exists by virtue of the relative positions (configurations) of the objects within a physical system.
 Potential energy is the dormant energy stored inside any physical system due to the nature of its configuration and presence of a force.
 Potential energy is the capacity for doing work that a body possesses because of its position or condition.
 The definition of gravitational potential energy is extended to unit mass to define gravitational potential.
 Now, we can use the “known” expressions of gravitational potential to determine gravitational potential energy of a system, including rigid body.
 Answer: There r two main types of mechanical energy they r potential energy and kinetic energy.

 Magnetic potential energy is closely related to electric potential energy, since both types of potential are mediated by the electromagnetic field.
 At its lowest point the kinetic energy is at maximum and is equal to the decrease of potential energy.
 That decrease is enough to compensate for the increased potential energy associated with lifting the fluid near the walls of the container.
 For example, when you run, your body converts stored chemical potential energy from your muscles into the kinetic energy of moving your legs.
 MeV is Mega electron Volts, where one electronVolt (or eV) is the change in potential energy by moving one electron up a 1 volt potential.
 During a phase change however, the potential energy of the substance changes as the particles are moved further apart or closer together.

 Thermal energy also means the potential energy of the object.
 In the case of liquids and solids there is also potential energy (of interaction of atoms) involved, and so on.
 For atoms that become less stable upon gaining an electron, potential energy increases, which implies that the atom gains energy.
 Chemical energy, for example, is the electrical potential energy stored in atoms.

 The Lagrangian for classical mechanics is taken to be the difference between the kinetic energy and the potential energy.
 The difference in potential energy is equal to the difference in kinetic energy.
 However, the difference in potential energy at different values of r – the quantity we are actually interested in – takes the expected sign.
 As n decreases the potential energy of the system becomes more negative and the electron becomes more confined in space.
 Using this convention, potential energy is zero when r is infinitely large, and negative at any finite r.
 The gravitational binding energy of a system is equal to the negative of the gravitational potential energy.
 In other words, we can only actually use this formula to measure the difference in potential energy between one nonzero separation and another.

 These classifications overlap; for instance, thermal energy usually consists partly of kinetic and partly of potential energy.
 As the object falls, that potential energy decreases and is translated to motion, or inertial (kinetic) energy.
 The mechanical energy of a system is the sum of its kinetic and potential energy.
 The energy released by fission and fusion is not just a product of the potential energy released by rearranging the nuclei.
 This basically accounts for the potential energy (that manifests itself as kinetic energy upon fission) as extra rest mass.
 As a potential energy source, nuclear fusion is even more powerful than fission.
 For example, a hydrogen atom that absorbs a photon of light converts the energy of that radiation into electrical potential energy.

 Mechanical energy  In physics, mechanical energy describes the sum of potential energy and kinetic energy present in the components of a mechanical system.
 Both components are often due to ion gradients, particularly proton gradients, and the result can be a type of potential energy available for work in a cell.
 The specific energy (energy per unit mass) of any space vehicle is composed of two components, the specific potential energy and the specific kinetic energy.
 The capacity for doing work as measured by the capability of doing work (potential energy) or the conversion of this capability to motion (kinetic energy).
 In this example the potential energy is stored by doing work against the force of gravity.
 Potential energy has many different forms, each arising from the specific type of interaction, such as gravitational or electromagnetic.

 In this figure, v represents velocity, F represents force, KE represents kinetic energy, and represents potential energy.
 However, when there is no force acting upon a particle its potential energy is zero and the Schrödinger equation for the particle can be exactly solved.
 Assuming no change in the height of the particle, this will be the total gravitational potential energy of the particle at all times.
 The orbit can be open (so the object never returns) or closed (returning), depending on the total energy (kinetic + potential energy) of the system.
 Energy of an Orbit The Total energy of an object in orbit is the sum of kinetic energy (KE) and gravitational potential energy (PE).
 He figured that the farther away the electron is from the proton, the greater the potential energy is inside.
 Things that are way up high have more potential energy than things that are way down low because they have farther to fall.
 Potential energy can be defined as the capacity for doing work which arises from position or configuration.

 Chemical energy is potential energy until the chemical reaction puts atoms and molecules in motion.
 Chemical potential energy is a form of potential energy related to the structural arrangement of atoms or molecules.

 The potential energy function for alpha particles near or within nuclei can reasonably be approximated as shown in Fig.
 The potential energy is a function of the state a system is in, defined relative to an arbitrary reference energy.
 Potential energy, in this instance, is simply a function of gravity and the distance h above some reference point.
 The total energy in this case is the sum of the kinetic and gravitational potential energy, and is conserved.
 In the reference frame of the planet, the sum of kinetic energy and potential energy is conserved.
 The potential energy is V=mgrsin(θ) where g is the acceleration due to gravity.
 First, consider gravitational potential energy near the surface of the earth where the acceleration due to gravity (g) is approximately constant.
 The height of the dot is directly related to the potential energy and the slope of the line gives the speed which is related to the kinetic energy.
 Escape velocity Escape velocity is the speed where the kinetic energy of an object is equal in magnitude to its potential energy in a gravitational field.
 When the positive and negative charges come back together, they speed up, so we say kinetic energy is gained and potential energy is lost.
 At point C, the potential energy is dependent upon the height, and the rest of the total energy is kinetic energy.
 At the same point, kinetic energy will have reached maximum value, and will be equal to the potential energy the ball possessed at the beginning.
 Likewise, the potential energy available for moving electrons from one point to another is relative to those two points.
 Now it is important to note that the potential energy is zero as the distance between the two masses goes to infinity.
 If the potential energy is set to zero at infinity, the usual convention, then bound electron states have negative potential energy.
 This is total potential energy of the shell, which is equal to work done in bringing mass from infinity to form the shell.
