Potential energy comes in a variety of types, but the two most common types are gravitational potential energy and elastic potential energy. Both types come with a very useful mathematical formula to go along with them. Gravitational Potential Energy Gravitational potential energy is the energy contai...

Noun1.potential energy- the mechanical energy that a body has by virtue of its position; stored energy P.E. elastic energy,elastic potential energy- potential energy that is stored when a body is deformed (as in a coiled spring) mechanical energy- energy in a mechanical form ...
Potential energyis present in an object that is affected by a force field. One example is water in ahydropower plant. Calculations of potential energy are made according to the following formula (2.2)E=m·g·h whereEis the energy (J);mis the mass (kg);gis the gravity acceleration (m/s2...
If the potential energy barrier of the shell is finite, then the wave function outside of the shell is not zero. The spherical potential in Figure 9.12.1 must therefore have a finite value and a finite thickness. It is assumed that the potential V(r) is constant over the thickness a of...

Kinetic energy is the energy of motion. Potential energy is converted to kinetic energy when the object in question begins to move. There are three types of kinetic energy: vibrational, rotational and translational. Each type of kinetic energy is named according to the type of movement the objec...
Because the gravitational force is conservative, we can express work done by gravitational force in terms of the change in potential energy, or W_{g}=- \Delta U_{g} . 可得: W_{app}=\Delta K+\Delta U_{g} Note that the right side of this equation represents the change in the mec...
In what way does the potential of a body differ from its potential energy? (Express in terms that apply to situations that involve electric and gravitational fields.) Describe a system in which elastic potential energy is stored. What is the difference ...
