E = mc² Calculator

E=mc2 special Relativity equation:

The energy of the object E(j) in joules is equal to the mass of the object m(kg) in kilogram and multiply square of  the speed of the light c2(m/s) in meter per second.Hence the E=mc2 special Relativity equation can be written as

E(j)=m(kg) *c2(m/s)

Where

E= energy of the object

M =mass of the object

C= speed of the light and value is 299,792,458 m/s

Example:1

Calculate the Einstein mass energy if the mass is 25kgs?

Answer:

Given that

Mass of the object m =25kgs

Speed of the light c =3*108 m/s

Energy of  the object E= m*c2

E=25*(3*108)2

E=25*9*1016

E=2.25 *1018

Therefore, energy of the object is 2.25 *1018 joules

Example:1

Calculate the Einstein mass energy if the mass is 32kgs?

Answer:

Given that

Mass of the object m =32kgs

Speed of the light c =3*108 m/s

Energy of  the object E= m*c2

E=32*(3*108)2

E=32*9*1016

E=2.88 *1018

Therefore, energy of the object is 2.88 *1018 joules
