Correctly.


1) Explore the energy storage in a rubber band.
a. Do you do work when you stretch a rubber band? How do you know?
b. How is energy stored in the rubber band? In what form?
c. How can you get the energy back from the rubber band?
d. How could the rubber band do work on a different object by using its stored energy?


2) Explore energy storage in a book
a. Do you do work when you raise a book from the floor to the table? How do you know?
b. How is energy stored in the book? In what form?
c. How can you get the energy back from the book?
d. How could the book do work on a different object by using its stored energy?

First person to answer both correctly, by 11:30 eastern time gets 50 points. 25 points for each question.

help? lol

Wow...good luck with this

I might have known the answer 10 years ago

Hahaha.

I was about to waste my time on this, then saw you are not PRO. You can only transfer 2 points a day.

But here is a link for your rubber band answers

Have fun with your physics home work.

lol 50 points to me is no biggie, transfering per day wouldn't be too bad =]

[HotStreak]

Shouldn't you be doing your homework now? You lazy fuk.

yeah pretty damn lazy. Hate this elective, and don't really care too much for it.

Fvcking kids on here

I have my education now I'm looking for winners..

Fvcking kids on here

lol I see that anyone in the range of 18-22 are all kids .... sorry to be too young compare to you

[D3 Mighty Ducks]

I'm 30 I am not old. You on the other hand are a kid, enjoy it while it lasts.

Good luck on the Physics homework

being 22 isn't quite a kid either, but *shrug to each its own.... lol thanks, just a random bs class I "need"

1.
a. Yes. You are applying an external force in the direction that the rubber band stretches. Of course, if you stretch it in both directions an equal distance, zero net work will be done.
b. Energy is stored within the rubber band in the form of elastic potential energy.
c. By releasing the rubber band back to its unstretched length.
d. By releasing the rubber band and causing it to apply a force on an object as its elastic potential energy is converted to kinetic energy. For example, releasing it behind a small toy car would cause the car to travel in the same direction as the force, so work would be done.

2.
a. Yes. You are moving a book a distance y above the ground by applying an external force when you lift the book. The force is in the direction of the motion (upwards) so work is done. (W = Fd)
b. The energy is stored within the book in the form of potential energy.
c. By lowering (or dropping) the book back to it's original height off the ground.
d. By dropping the book onto an object so that it travels a distance. For example, dropping the book onto a spring will cause it to compress, so work is done on the spring (by the book).

Dang should have checked this before I tried to do it myself... lol but u get ur 50 point anyways...2/day
