See, this is why I never took physics. Stuff like this makes my throat close up. I can remember the simple basics:

#1 = A body in motion tends to remain in motion; a body at rest tends to remain at rest.

#2 = Force equals mass times acceleration. (But then you start quibbling over the math and I just want to go (##$#)@&#$(*%)!!

#3 = For every action there is an equal and opposite reaction.

That's all the physics I want to know. Now leave me alone.
