Force: Penguin Dictionary of Science

[RascalPuff]

"Force:
An external agency capable of altering the state of rest or motion in a body; measured in newtons (SI units), dynes (c.g.s. units), or poundals (f.p.s. units). The force, F, required to produce an acceleration, a, in a mass, m, is given by F=ma. If m is in kilograms, a in metres per sec. per sec., F will be in newtons."

Force;Flowing
On/In
Realized
Conscious
Energy=Force!

Force the presence of power,flowing energy from unlimited source.

Is there any "real" difference between the words,force,power,energy,or are they all one
of the same thing,perceived rather differently.

Dear Physics Professor RP,

Thanks for helping me understand f, but like any good student, I have a couple of f questions.
I was wondering the measurable f it took using your formula of course, for me to respond to your enlightening thread. To help you help me I can tell you I weigh 200 lbs. which I think converts to 90.7184 kilos give or take a zero? As far as a or acceleration, I am completely at rest at my desk, although my brain is moving as usual, ever so slowly, and or unless you take into account my motion as the earth turns, and as the earth rotates around the sun, and as the solar system spins, and as the galaxy turns, and as the universe expands. Do you count all or any of those motions to find f? If so than how many meters per second is that? Oh, and what about the time it took to respond, response time or RT, which is like you RP? Anyway, how many newtons did it take me to respond or as you say, f? For your solution to f, I'll bring you a Newton apple someday for the energy or f it took for you to respond back to me!
Thanks,
Your physics student in the back row,

Thanks for your confidence MJA, but mathematics is not my forte. Even it if was, I'd have a lot of computations to make as to how many forces are acting on quite anything at all - at any given moment - and to what degree.

I'm posting definitions to clarify meanings that sometimes qet a little hazy in their usages as far as definitions go. Hey. The thread in itself is merely based on an excerpt from a science dictionary. I expect that this thread may be used as a reference as well as become more colorul and informative, with additions from entrys such as yours.

Best regards,
