AWESOME!
Thanks for that.
Tell me please though, if I did write x to be x - B/A then I think I should be using x - B/A for the potential energy as the x there: 0.5Kx^2. Correct?
:)
actually I did guess.
Well, I mean, I figured because it was the coefficient of x, then it would be reasonable to assume that, that is K.
X would be the answer for the differential equation I got previous.
mx?
why am I meaning mx? m as in mass? and x as displacement?
Then where does K come in?
(I am not being disrespectful I hope, I really liked your comment, which made me laugh, because I really do not know why should I use mx)
:)
true... forgot that for a sec... but is this the equation I should go for?
K being a function of x? Then the whole potential energy is going wrong, because K is not constant, or does it? ( I think K should be constant to use k(x^2)/2)
:)
Did not think of it this way.
But then, what will be 'k' equal to?
How do I work the algebra for it?
and will the potential energy of it all will indeed be k(x^2)/2?
The problem was:
A cylinder is placed inside water, and it is in equilibrium when half of the cylinder height is submerged. So I Know there is the archimedes principle which causes a force upwards and then there is gravity downwards. This problem was part of question somewhere, but in the...
Hey all,
I have seen that these two forces combined together have the potential energy of a spring with a constant 'K' as a combination of some sort of the two forces.
I have no idea how am I to find this K.
All I know
Mgh + ρVgh gives the potential energy of a given system let's say.
help?
Unfortunately, I am unfamiliar with the first 2 theorems, but I can explain you the superposition one.
Imagine, for instance, you have got a known amount of charged particles in space, and you would like to know the electric field at a specific point in space, you would simply add each force...
AWESOME!
Thank you SO much for your patience. I do have an upcoming test which most definitely will include this kind of question. I tried to understand this subject for like a month, and in a few hours doing this question have proven VERY valuable.
Thank you!
