Title: particle in 3-D
Post by: kushal on April 09, 2007, 01:38:25 am
when a particle moves in x,y,z axis then how does tthe position vectors or values of x,y,z changes? i have been searching this to study galilean and lorentz transformations but unable to find one. if any of you wanna discuss, mail at mr.kushal.gupta@gmail.com                  v can fix a time to chat. thankyou

The position of x will be determined by vx: (similar conditions for y,z)

 x(t)=x(0)+vx *t (if velocity is a constant value).
 x(t+dt)=x(t)+vx(t)*dt (if velocity is not a constant, and dt is a small time interval).
The complete integration can be calculated with numerical method. For example: I use Runge-Kutta 4th order method for all the simulation in this web site.
