wait till you graduate and realize you:

a) dont need any of it unless youre specifically going to major in it

b) wont ever use it

c) dont remember any of it anyway

I could sit here and type my *** off about the subject but that won't do anyone any good. Let us know what areas you need help with and we'll see what we can do.



I know motion in 1D, 2D, angular velocity, jerk calculations through derivatives of a slope tangent equation etc etc. like the back of my hand, so chances are I can help you out.



But then again, you should be able to master that in seconds, it's easy **** LOL.

We're just getting into rotational and cyclic kinematics. Simple harmonic motion, uniform circular motion, regular circular motion, and eventually, I've heard, elliptical/gravitational motion. Everything is heavily calc based. Calc 1 is prerequisite and calc 2 is required simultaneously.

Striker - Thats exactly what yesterdays lecture was over. I need to be able to understand something conceptually before I can understand it mathematically. And all those damn greek letters don't make it any easier to understand.

Eyxom - Do you know any good websites or books that explain more the concepts than the math? Thnx.



Oh, and Lee - the answer is not 27, its 42.(see sig)
I don't know any sites in particular, but if you explain the scenario and the math, I can relate it to you in English so-to-speak.



Conceptual question of the day: How does a rocket's thrust continue to work in the vacuum of space?



Answer to come tomorrow.

isn't the momentum of the gases leaving the thruster that provide the opposing force?

Does anyone here understand physics? Im in physics now and were doing circular motion with angular velocity and tangential acceleration. I dont have any idea whats going on. Any input?
Isn't that what rocket science is base on?
