Thank you so much for helping me out here. I finally 100% got it. Time to figure out conservation of energy in 2 dimensions :P Thanks again.

Hi, thank you again, you are really helpful. Sorry the wrong terminology. So, if I got it right, for a mass hanged by a spring from a ceiling, ΣF =-mg-kx (the spring's equalibrium = 0 potential energy, so gravity can take values of minus potential energy whenever the mass is beneath the...

When I say that I integrate from x2 to x1 I mean that I set x2 as the upper bound and x1 as the lower bound of the integral. You mean to set x1 as the upper bound and x2 as the lower bound in order to calculate the work? I thoughts you do it in order to find the potential energy (hence the minus...

Hi, thanks for replying. I evaluate the overall work done between the starting point (x1) to the end point (x2), so I integrate from x2 to x1 (the value at x2 minus the value at x1 gives me the work done between). I got something wrong?

Hi, I looked around for hours but it seems like I'm the only one who finds it confusing. I understand the concept of potential energy and work, but have a problem with the equations. Here is what I don't understand: The work energy theorem states that K2-K1=W. W = ∫Fdx from evaluated between...
