Original project How to determined the trajectory of a planetary motion (http://www.phy.ntnu.edu.tw/ntnujava/index.php?topic=629.0)

The question is why I can draw the trajectory when you change the initial condition with you mouse.
(You can drag the red arrow  to change the initial position and magnitude of velocity(vy).
How to determine the trajectory?  Do you know?
