    Potential Energy (A box attached to a spring which is attached to the ceiling.)

    This makes a lot more sense to me. Thank you, hikaru! :approve::cool:

    Potential Energy (A box attached to a spring which is attached to the ceiling.)

    Ok, I made a diagram to bring some clarity to the confusing mumbo jumbo I have written :P Like I stated earlier my confusion lies within the fact that you can use x as the height in the equation Ep. Why is this viable? I thought you needed the height of the object ABOVE the ground. So why...

    Potential Energy (A box attached to a spring which is attached to the ceiling.)

    I solved the question already during the test, and got it correct. I just wanted to know the reasoning behind why Ep is still usable in a direction against gravity. I thought the whole reasoning behind Ep was that when an object is lifted from the ground upwards, it's potential energy is...

    Potential Energy (A box attached to a spring which is attached to the ceiling.)

    The length in the stretch of the spring is represented by x. And x can also be used as h. Ee=(k*x2)/2 Ep=m*g*h After substituting all the values, k can be solved for.Edit: that is correct, 6stang7.

    Potential Energy (A box attached to a spring which is attached to the ceiling.)

    I can. I just really wanted to know why it is that you can use Ep to solve a question like this. I also asked my teacher this question after the test, and she told me as well it's all relative. But then I asked her why you can use gravity? Especially if the acceleration of gravity is in the...

    Potential Energy (A box attached to a spring which is attached to the ceiling.)

    Hello everyone! To start things off, I apologize if this thread does not go here. Today I had a test on Energy (Potential, Kinetic, Elastic) and we had a question which asked us to find out the value of k for a spring. The question was centered around a box hanging from a ceiling via a spring...

    Linear Momentum (One Dimension) Quiz Question

    Yeah, sorry, the mass of the jacket is 1kg... >_> Thanks for the quick reply! I guess I need to work on thinking clearly during tests/quizzes.

    Linear Momentum (One Dimension) Quiz Question

    Hello forum, today in my gr. 12 physics class I had a interesting question which I could not prove at all for the life of me. It is a really simple question, just with a little twist I suppose. As I was driving home from class I was thinking about what I was missing and thought up a solution...
