"Froce is speed x mass" - Oh dear god!
Newton's law do not hold for things with very large mass, or for things at very high speed. Light travels at very high speed. As such, you cannot use Newton's laws to try to explain it (even if you manage to state said laws correctly).
Light is massless, but it still has a momenteum, or impart a force. If light had a mass, it would not be able to travel at light speed!
This can only be understood by modern physics. This is why newtonian physics is reffered to as "classical" physics.

I am currently involved in research on colour vision in the periphery. On my reading I have discovered that "visual receptors can absorb and respond to as little as a single photon of light" (Kalat, 2001, p152).
Isnt what I said all along is that heat is the byproduct of the tranformation of onf one from of energy to another form of energy? It appears that you just argued my original case for me. Thanks.
Isnt somthing hot if it produces heat? whether it comes from energy transformation or not. If you run your hand on a spinning wheel Im willing to bet your hand will get hot. Thus your hand gets hot from the wheel so you could accurately describe the spinning wheel as hot.

And you are now changing the definition of heat.
Running your hand along a moving wheel will cause friction, which will generate heat. But by no means what-so-ever could you describe the spinning wheel to be hot.
Tape a thermometer to the spinning wheel, and you will find out how hot it is. It will be at room temperature. Rub your hand against it, and some of the kinetic energy will be converted by friction into heat energy, and the temperature will rise. The wheel is now hot, but it wasn't before you converted its kinetic energy into heat.
Without your intervention by no means could you claim the wheel was hot.
Now it appears, that you are not only wrong, but you are being arrogant about it.
