Question

what is kinectic energy?
work and energy both have the same unit I.e.joule why?

Answer 1

The energy possessed by an object when it's moving is called kinetic energy.

Since energy and work are two sides of the same coin, they are measured with the same units. The SI unit of energy/work is the joule (J), named for English physicist James Prescott Joule (1818 - 1889). Joule discovered the relationship between heat and mechanical work, which led to the development of the laws of thermodynamics.

Answer 2

Answer:

This is simply the change in kinetic energy of the object. Hence as energy is conserved we can now see that the work done on the object is equivalent to the energy supplied to the object. Therefore work is a type of energy, and so it is measured in the same units, Joules.
