Is Mass Real?
or is it just an accumulation of force?

"just"?
well, gravity is "just an accumulation of force" . . . but it is not mass. So hey, how about we have a word for the accumulation of force which makes . .. uhmmm . ..mass?

I think it is a reduction in acceleration....
Wanna get bigger? slow down Wanna lose mass? move faster

Mass is real and not an accumulation of force. If anything, mass resists force. Now if you apply a force to accelerate a mass that's another story.

Isn't mass just a term used to quantify the density of matter?
Can there be mass without matter...or, matter without mass?

We must be really bored!
Many people use mass and weight interchangably but technically they're not. I mean how many people buy a slug of grapes?

Energy is force over a distance. Power is energy over time.

Power is the rate at which work is done- like torque times speed.
Work and energy are equivalent- force over distance. Same units as torque/moment oddly. Foot pounds or pounds feet. My Dynamics professor says the order does not matter. Who is going to bring up String Theory vs. Standard Model's Higgs Boson?
