For a threefold increase in speed, the kinetic energy will increase by a factor of nine.
What is kinetic energy?
Energy is a physical quantity that allows a thing to perform labor. When an object performs work, only objects with kinetic energy, potential energy, or both (mechanical energy) can perform that work.
Since electrical energy is produced by an electric charge flow, it can either be potential or kinetic energy. Using a battery as an example, we can see that it contains electrical potential energy while charging.
Kinetic Energy's formula is KE = 1/2 mv2. Because mass and kinetic energy are directly correlated, an object's kinetic energy rises as mass does. The same may be said for velocity.
Due to the fact that kinetic energy is proportional to the square of speed, increasing speed results in an increase in kinetic energy.
