The above mentioned definition ( E mech = U + K) assumes that the system is free of friction and other non-conservative forces. The kinetic energy, K, depends on the speed of an object and is the ability of a moving object to do work on other objects when it collides with them.

The potential energy associated with a system consisting of Earth and a nearby particle is gravitational potential energy. It is defined as the object’s ability to do work and is increased as the object is moved in the opposite direction of the direction of the force. The potential energy, U, depends on the position of an object subjected to a conservative force. If only conservative forces act on an object and U is the potential energy function for the total conservative force, then See also: Conservation of Mechanical EnergyĪn isolated system is one in which no external force causes energy changes. The total mechanical energy (defined as the sum of its potential and kinetic energies) of a particle being acted on by only conservative forces is constant. It is dependent upon the spring constant k as well as the distance stretched.Įlectric potential energy is a potential energy that results from conservative Coulomb forces and is associated with the configuration of a particular set of point charges within a defined system. For example, if a positive charge Q is fixed at some point in space, any other positive charge which is brought close to it will experience a repulsive force and will therefore have potential energy.įirst the principle of the Conservation of Mechanical Energy was stated: The most common use of gravitational potential energy is for an object near the surface of the Earth where the gravitational acceleration can be assumed to be constant at about 9.8 m/s 2.Įlastic potential energy is potential energy stored as a result of deformation of an elastic object, such as the stretching of a spring. Gravitational potential (V the gravitational energy per unit mass) at a location is equal to the work (energy transferred) per unit mass that would be needed to move the object from a fixed reference location to the location of the object. In classical mechanics, the gravitational potential energy (U) is energy an object possesses because of its position in a gravitational field. It depends on the speed of an object and is the ability of a moving object to do work on other objects when it collides with them. The kinetic energy, K, is defined as the energy stored in an object because of its motion. Common types include the gravitational potential energy of an object that depends on its mass and its distance from the center of mass of another object. Potential energy, U, is defined as the energy stored in an object subjected to a conservative force. Stored mechanical energy exists in one of two forms: kinetic or potential: Transient mechanical energy is commonly referred to as work. Stored energy is the energy contained within a substance or object.

Transient energy is energy in motion, that is, energy being transferred from one place to another. M echanical energy (and also the thermal energy) can be separated into two categories, transient and stored. Let assume the mechanical energy (E mech), which is the energy associated with the motion and position of an object usually in some force field (e.g. Common types include the gravitational potential energy, the elastic potential energy of an extended spring, and the electric potential energy of an electric charge in an electric field and so on.
