Physics problem..please help!?

Question

Einstein's famous equation indicates that E = mc2, where c is the speed of light and m is the mass of the object. Given this, what is the SI unit for E ?

Answer 1

Energy (E) in the Système International (SI) is measured in Joules.

Answer 2

E = mc²

Hence E can be measured in kg.m²/s² (= joule)

Answer 3

Yes, the SI unit for energy is the Joule, which is the energy expended by a force of one Newton moving one metre in the force's direction. In other words, kg/m²•s².

Answer 4

E=mc^2=unit of m=Kg,unit of c=m/s c^2=m^2/s^2

therefore unit of E=Kgm^2/s^2
