Explain with examples the equation E=Mc square? By definition physics

This is the Mass energy Equivalence relation given by the Einstein which relates the Mass of any boody with the speed of light as its energy.

This recipe expresses that the equal vitality (E) can be computed as the mass (m) increased by the speed of light (c = around 3×108 m/s) squared. (Essentially, anything having vitality displays a relating mass m given by its vitality E separated by the speed of light squared c².) Because the speed of light is a substantial number in ordinary units, the recipe infers that even a regular question very still with an unobtrusive measure of mass has a lot of vitality characteristically.
