Thanks. I'll take a look at that.

I'm doing a research project on collisions and I've come across a part of my theory that requires solutions to coupled damped oscillators. Could anyone please refer me to some text on 2 coupled damped oscillators which isn't extremely math heavy and has conceptual explanations of the...

Resolve the final momentum of the car and truck into horizontal and vertical components and then use conservation of momentum for both the vertical direction and the horizontal direction.

There is a normal reaction force on the canon due to the ground. thus net external force in the y direction is not zero and thus momentum in the y direction is not conserved. The canon's y velocity with respect to the ground stays zero. This is one of the constraints on the system. This...

The period is given by the sine and cosine functions. The angular frequency of the sine oscillations in part a is 12 pi and that of the cosine oscillations is 13 pi. Thus T1 is 1/6 sec and T2 is 2/13 sec. Thus the period of combined oscillations T = 12*1/6=13*2/13=2sec Thus frequency...

Homework Statement Find the frequency of combined motion of the following (a) x = sin (12pi.t) + cos(13pi.t + pi/4) (b) x = sin(3t) - cos(pi.t) Homework Equations The book I'm using states that if the periods are commensurable ie if there exist 2 integers n1 and n2 such that n1T1 =...

Thanks for the link. As a complete novice in the realm of relativity I guess I get confused easily.

Oh wow! So my initial premise itself was wrong. Could you however explain your statement a little because I don't really understand why light would have no frame of reference. Is it to do with light being essentially zero dimensional. I always associated frame of reference with anything that...

But aren't shadows cast on a surface which at the molecular level will have irregularities making it a 3-d structure?

I don't think you can differentiate average velocity because in this case the limit dt -> 0 will not be valid.

Hi, I have a question which to many may seem quite stupid but it honestly has been perplexing me for a while now. I'm actually not sure if this is the correct place to post this but the question does seem to be based on the theory of relativity so here goes. I think I'm correct in supposing...

I apologise. I was just curious and I'm new to this.

I guess i can't really give an exact definition. I would say that traditional meant non zero rest mass but that's hardly a traditional definition.

Thanks. So photons aren't really particles in the traditional sense are they?. Their particle nature is just a reflection of the quantization of their energy.

What is solar wind?
