Hi, i wanted to know what formula i could use to plot a trajectory. Wouldn't it be something like a parabola? I know little on the subject so help would be appreciated.

Displacement=.5*acceleration*time^2 + Initial Velocity*Time+initial displacement.

Split it into x and y and you are good.

Hint:
X=r*cos(theta)
y=r*sin(theta)

Ever notice how in Microsoft word, the word "microsoft" is auto corrected to be "Microsoft" but "macintosh" just gets the dumb red underline?

x = v*cos(a)*t
y = v*sin(a)*t - ½gt²

v = velocity
a = angle
t = time
g = gravity


Did you want this in only 2D or 3D as well? My particle tutorial covers the equations and uses them in 3D. http://zimnox.com/?page=dbTutorials

@ bn2 - um, mind re stating that in a way that someone who hasn't done algebra or anything like that could understand and that would be good to go.

@Phalex - just 2d for now.

[edit] Never mind everyone, i got it now. Phalex's tutorial was big help. thanks.
