- Kinetic Energy and Its Expression
The energy possessed by any object by virtue of its motion is called its kinetic energy.
The kinetic energy of an object is a measure of the work an object can do by the virtue of its motion.
Kinetic energy is a scalar quantity.
If an object of mass m has velocity v, its kinetic energy K is
`k = 1 / 2 mv^2`
`= (p^2)/ (2m)`
where k=kinetic energy, m = mass of the object, U = velocity of the object and p = mv = momentum of the object.
