This equation describes the total (i.e., both potential and kinetic) energy of the body. To obtain the relativistic kinetic energy, you need to subtract the potential energy (previously found with the potential energy formula) from the total energy: \small\rm KE = E - PE KE = E −PE. The potential energy, in this case, is equal to the rest

The work-energy theorem states that the net work done by all forces acting on a system equals its change in kinetic energy (KE). In equation form, this is: Wnet = 1 2mv2 − 1 2mv2 0 = ΔKE. If only conservative forces act, then Wnet = Wc, where W c is the total work done by all conservative forces. Thus, Wc = ΔKE.

Elastic potential energy is energy stored as a result of applying a force to deform an elastic object. The energy is stored until the force is removed and the object springs back to its original shape, doing work in the process. The deformation could involve compressing, stretching or twisting the object. Many objects are designed specifically

Kilowatt. Definition: A kilowatt (symbol: kw) is a unit of power in the International System of Units (SI). The base unit of the kilowatt is the watt, which was named after Scottish inventor James Watt. As is consistent with SI units, the prefix kilo- means that a kilowatt equals one thousand watts or one thousand joules per second.

Since one kilovolt is equal to 1,000 volts, you can use this simple formula to convert: volts = kilovolts × 1,000. The voltage in volts is equal to the voltage in kilovolts multiplied by 1,000. For example, here's how to convert 5 kilovolts to volts using the formula above. volts = (5 kV × 1,000) = 5,000 V.
