Kinematics Point Mass Dynamics
Motion of a Point Mass change in position d (this can be either x or y) change in speed dv (this can be either vx or vy) d = d + dv*dt + 0.5*da*dt*dt dv = dv + da*dt
Polar to Cartesian Coordinates x = r * COS(rads) y = r * SIN(rads)
Rotation of a Point (x,y) Around (0,0) xt = x yt = y x = xt * COS(rads) - yt * SIN(rads) y = yt * COS(rads) + xt * SIN(rads)
Converting from World Coordinates to Display Coordinates p = pmax * (d - dmin)/(dmax - dmin) 0 pymax py . px 0 pxmax
