Haha, well my lab backs it up. I'm just never very sure.. because.. it IS a physics lab. Thanks!

Homework Statement Well, this isn't really a number question, but I'm wondering if the larger the k of a spring, if that will make the energy transformation of a weight from potential energy to spring energy more efficient? Homework Equations F=-kx ; energy before = energy after The...

HAHA. O goodness. That's great. Because here I am sitting in high school trying to make some sense out of this. Thanks for your help!

.. I'm still as confused as I started out to begin with...

So I've been looking online @ Schrödinger's Equation, but I still can't get a good grasp of what it's all about... All I know so far is that its part of quantum mechanics and that its solutions describe atomic and subatomic systems, electrons and atoms.. <---but what does that actually mean...

never mind figured it out.

Here's my value: length: 8.25 +/- 0.05cm If I convert 8.25 to m how to I .. convert my uncertainty?

o goodness. Yes I DO have a lot more to worry about. Which means I need to find the spring constant. What does the K mean? in F=k delta x ? Is there a way I can find x with info only about force? I'm not sure I even have k...

ok ok hold on, my question here is though I have 2 carts with springs at the back of them and I've pushed them together and realeased Then in order to prove that energy has been conserved, I'd need to calculate the elastic potential energy right..?

o dear. sigh. I have a lot more to worry about now thanks

Is there a difference between the "law of conservation of energy" and "law of conservation of kinetic energy?" If so what is it? and what IS the law of conservation of kinetic energy? It doesn't seem to be in my textbook or on the net..

its actually about the conservation of kinetic energy ... so would it be conserved? I mean there would be elastic potential energy right.. ?and that would transform into kinetic energy?!

So yes that's the question: In a cart explosions (where 2 carts with springs on the back are pushed together and let go) is the kinetic energy conserved? If not why? I can't find it in my textbook or on internet sites (things specifically related to cart explosions anyways) But attempting to...

ok well I', doing a pendulum lab. And I graphed period against amplitude, then I linearized it.. in order to do that , I had to square my x-axis units which was amplitude (deg) so the slope is s/deg^2 And I'm just wondering what it might mean..
