When energy is applied to a mass does the mass increase?

Question

When energy is applied to a mass does the mass increase?

Answer 1

If we are to look at it based on of Einstein's Relativity using the Lorentz transform then the answer is yes. The Lorentz transform is;

m' = m(1 - v^2/c^2)^(-0.5)

Where;

m' = relativistic mass

m = rest mass

v = velocity

c = speed of light

This means that the mass increases as the velocity increase and since an increase in velocity is due to the application of energy then we can say that mass increase with the application of energy.

Answer 2

Energy IS mass.  So yes, adding energy adds mass.

For example, adding Kinetic Energy (velocity) adds mass.  Heating to add Thermal Energy (velocity of the particles inside) adds mass.  Lifting an object to add gravitational potential energy adds mass.  Changing chemical bonds to add chemical potential energy adds mass.  Normally the increase in mass is so small it is hard to measure.  E=mc^2 implies a small increase in m gives a big increase in E.

Bottom line:  Energy IS mass.  Adding energy adds mass.

Answer 3

this is especially seen with atoms with electrons. the mass of the atom increases because of the movement of the electrons.

Answer 4

No. It is not possible to add mass by adding energy, though the equation shows E = m*c^2 they are interchangeable. In theory only it is possible just as only in theory we can approach the velocity of light.

Answer 5

cant say like that.. bur mass can turn into energy... E=mc2
