Potential energy is the energy by virtue of an object's position relative to other objects. [6] Potential energy is often associated with restoring forces such as a spring or the force of gravity. The action of stretching a spring or lifting a mass is performed by an external force that works against the force field of the potential.
1.2×10 19 J Explosive yield of global nuclear arsenal [202] (2.86 Gigatons) 1.4×10 19 J: Yearly electricity consumption in the U.S. as of 2009 [181] [203] 1.4×10 19 J: Yearly electricity production in the U.S. as of 2009 [204] [205] 5×10 19 J: Energy released in 1 day by an average hurricane in producing rain (400 times greater than the ...
The electric potential and the magnetic vector potential together form a four-vector, so that the two kinds of potential are mixed under Lorentz transformations. Practically, the electric potential is a continuous function in all space, because a spatial derivative of a discontinuous electric potential yields an electric field of impossibly ...
The electrostatic potential energy of a system of three charges should not be confused with the electrostatic potential energy of Q 1 due to two charges Q 2 and Q 3, because the latter doesn't include the electrostatic potential energy of the system of the two charges Q 2 and Q 3.
Potential energy – energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors. [3] [4] Elastic energy – energy of deformation of a material (or its container) exhibiting a restorative force; Gravitational energy – potential energy associated with a gravitational field.
Energy profiles describe potential energy as a function of geometrical variables (PES in any dimension are independent of time and temperature). H+H2 Potential energy surface. We have different relevant elements in the 2-D PES: The 2-D plot shows the minima points where we find reactants, the products and the saddle point or transition state.
The potential has units of energy per mass, e.g., J/kg in the MKS system. By convention, it is always negative where it is defined, and as x tends to infinity, it approaches zero. The gravitational field, and thus the acceleration of a small body in the space around the massive object, is the negative gradient of the gravitational potential ...
