ORIGINAL: RedMagic1 Holy mackerel. Are you this ignorant about everything you post? "Correcting" someone like this is just as bad as what the OP and her, uh, master, tried to do. I'd ask you the same question. Your holier than thou attitude has obscured your knowledge of the facts. And your correction is incorrect as well. quote:
ORIGINAL: RedMagic1 Shockingly, force equals mass times acceleration is usually written F=ma... just the way Newton did it. F=ma is Newton's second law, which is not about force equaling mass times acceleration, but rather that an applied force on an object equals the rate of change of its momentum with time. Since the second law applies to an object with constant mass (dm/dt = 0), the first term vanishes, and by substitution using the definition of acceleration, the equation can be written in the iconic form F=ma.
