BSRComb your hair if you want people to take you seriously. Sheesh...

newtboyHmmmm….
K.E. = 1/2 m v2
E = m v2 (only when v=c)
Does equation 2 include equation 1 or not?
Does total system energy E = 1.5m v2 (kinetic energy + mass-energy) or is the equation really E = 1/2m c2 + (K.E.)?
Anybody?
luxintenebriswell...i'd say 1/2 m is an 'n'; v2 was a rocket; and K.E. is my cousin's initials...if that helps?

newtboyNot so much, but thanks for playing.

BSRSorry. I slept in math class. Boooring.

newtboyHa!
No problem, but this would have been from physics.
Sorry. I slept in math class. Boooring.
noimsActually, I think I can verify this. I remember in physics going through a derivation of why E=mc^2 and being very disappointed that it was just a specialised case of your second equation.

BSRYou're just showing off now. Just trying to make me look stupit.

newtboyGood, then I’m not just being dumb….But you don’t recall at what point it goes from KE= 1/2m V^2 to E= M C^2 …or the equation/function used to determine energy below the speed of light but above the 1/2 threshold?
Somewhere below C (speed of light) it gains up to 1/2 the total system energy, beyond simple kinetic energy…I’ve heard this alluded to as mass becoming energy, but never with any explanation how or even if that’s reality or just a mathematical “trick” to make the equations work…nor an equation describing the process. I only took year one physics….over 25 years ago.

luxintenebrisat least it is not in person.
a squirrel dropped out of a tree and landed on the hard dirt in front of myself & a friend. it then* quickly srambled up a nearby tree.
the friend then explain why the squirrel wasn't hurt. went off on a soliloquy** on terminal velocity. after he was finished told him...
"that wasn't the question i would have asked. i want to know why it fell. we just trimmed that tree, so did the squirrel try to make a longer leap or just - out of habit - jump to a phantom limb?"
we just stared at each other for a while.
*swear it made an 'eep' sound when it landed. like a dog toy.
**i sure wasn't listening

BSRMaybe it was just...nuts?
