Everyone drops stuff. An object at rest at a distance above the ground has a positive potential energy value (mgh) and a kinetic energy value of zero (1/2m(v)(v)). Once I released the pencil, its potential energy started to drop and its kinetic energy started to rise. Right before the pencil hits the ground all of the potential energy has changed into kinetic energy. The kinetic energy right before the pencil his the ground is the same value as its potential energy at the top because of the law of conservation of energy. However, the pencil does not bounce back up to its original position because most of its energy is converted into heat, sound, transfered to the ground, or other converted into other energy.
Hi Kevin (:
ReplyDeletethe last line..... "or other converted into other energy."
LOVE IT. just kidding
wow this is really kicking me out of the quote huh??
LOVE YOUUUU YUGA
nice pictures!!
ReplyDeleteDang, you managed to talk about what we were learning without making it complicated like I did...kudos. Wish I could have thought of that :)
ReplyDeleteEveryone drops stuff except for you when you step out onto the gridiron. Excellent use of the physics we learned
