We are learning in class about kinetic and potential energy and how it is 
created and transferred. How does kinetic energy transfer to radiant energy? 
For example if you heat up a plate of iron and it starts to glow, what amount 
of kinetic energy is needed for it to emit the photons (Is kinetic energy not 
a fixed amount like photons?)? Or say to accelerate/rotate an atom how fast and 
what energy level needs to happen until it emits a photon, and how?
