Question

I was wondering if Newton's first law of motion applied to the reaction that elements go through when heat is applied. When an electron in a quantized orbital is heated it will move to another quantized orbital, release energy as a form of colored light, and then move back to it's original position when the heat is taken away. Before the heat was applied the electron had potential energy, and when the heat was present it converted to kinetic energy. The electron would not have switched orbitals without the presence of an outside force, It would have just forever kept doing what it was doing.
