Lifting an object away from the earth’s surface gives the object gravitational potential energy because the object has moved against the earth’s gravity. A helicopter has gravitational potential energy.
Gravitational potential energy
Elastic energy
Electrical energy
Chemical energy
Stretching a rubber band gives the rubber band electromagnetic potential energy because the rubber band’s molecules have been forced apart, overcoming the molecules’ electromagnetic attraction.
Electrical energy
Gravitational potential energy
Energy of motion.
Elastic energy.
Applying a voltage to a conductor gives the conductor electromagnetic energy because the electrons have not yet yielded to the electromagnetic force.
Thermal or heat energy
Electrical energy
Gravitational potential energy
Thermal into Chemical.
The electrons in molecules of fuel have electromagnetic potential energy. They are too far away from the nuclei of the product that can be formed during combustion.
Electrical to Thermal.
Resistance
Energy Conversion
Chemical energy.
Changes among solid, liquid, and gaseous states are electromagnetic potential energy because the molecules have overcome the attraction between electrons in one molecule and the nuclei of neighboring molecules.

Energy of motion
the opposition that a device or material offers to the flow of direct current. The symbol is R and the unit is ohm, which is represented as Ω.
Resistance
Friction
Potential Energy
Kinetic energy.
the resistance that one surface or object encounters when moving over another.
