Couldn't sleep last night; old news.
Thinking about too many things; old news.
Some things I contemplate make sense considering my present situation, while others, well, lack relevance to anything pertinent...e.g. this sentence.
At four AM-ish I was considering the whole "conservations of energy transfer", (for non-nerds, the basic principle that energy can't be destroyed) and applying it to bouncy balls. Yeah.
See, I got this strange questioning about where the energy goes when (for god knows why) you decide to drop a bouncy ball on a surface that doesn't absorb heat and creates no friction. Assume the ball drops with translational, linear motion, and uh, no hysteresis with the springiness of the bouncy ball ok. Say it's in a vacuum too.
Now, from the height above the surface, the ball's got gravitational potential energy (PE)--and when it falls to surface, that goes to kinetic energy (KE), then absorbed by internal springiness of ball when it hits the ground. And, if you've had physics you know that the spring potential is elastically converted back to the balls KE making it bounce= gain PE from converted KE. ect. Yay HS physucks!
Actually, any(every)one who's ever own a rubber ball ought to get the gist of this. Anyhow, point is, you also know that eventually the ball stops bouncing.
My question was and still is, where does the energy go? I've read that you're supposed to resort to assuming the molecules of the ball and ground absorb the random "disappearance" of energy(?) Something about entropy evolving or something...I sucked at physics. But anyhow, from a chemistry view, this confuses me further. If the molecules absorb energy, their bonds will be vibrating (if they absorb enough, they break apart) and if you dropped the ball from high enough, that sure would be a lot of energy to absorb over time until the ball stopped. (i.e. the ball's molecules or the grounds' bonds ought to be breaking apart, if I follow the laws, right? Like mass explosion...except that's not what you observe, obviously. So uhmm...
Could it be, when the ball stops bouncing up, off the ground, it just continues vibrating--invisibly to the naked eye--for all eternity? Maybe it get's enveloped by the omnipresent ether or something. Can anyone explain this?
cuz I'D LIKE TO KNOW so that I can sleep. I don't even know where to look it up.
I've already given up seeking explanation for how or why I contrive these pointless ideas.
Anyhow.
Speaking of momentum, I've been surfing a swell-mood-undulation that's steadily rising => "good". I attribute it partially to the bright n'sunny, warmer weather (45 degrees Yayaya! :cough:) I've also come to realize that wallowing in a stagnant, cynical state for too long makes one unhealthy--as in physically ill. I had reached the point where I only left my room to attend class. In summation, it's grown more than imperative to end the dramatic polarity.
P.S. I can't really explain why I'm so antisocial. To allay any worries (or hopes?), I'm not depressed or drawing up elaborate plans for suicide. I suppose, when it's really cold and everyone's stressed, I openly welcome these states of apathetic bliss.
Conversely--sometimes, I'm just contemplating bouncy balls.
