Kinetic energy of an object is the measure of the work an object can do by the virtue of its motion. Kinetic energy is a scalar quantity. Kinetic energy is completely described by magnitude alone.
Kinetic energy equation
- The SI unit of kinetic energy is Joule which is equal to 1 kg.m2.s-2.
- The CGS unit of kinetic energy is erg.
The equation for kinetic energy can be expressed as
- K.E = Kinetic energy
- m = Mass of the body
- v = Velocity of the body
Example of K.E
The kinetic energy of the aeroplane is more during the flight due to large mass and speedy velocity.
