This following applet is How to determined the trajectory of a planetary motion?
Created by prof Hwang Modified by Ahmed
Original project How to determined the trajectory of a planetary motion

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?

• Please feel free to post your ideas about how to use the simulation for better teaching and learning.
• Post questions to be asked to help students to think, to explore.
• Upload worksheets as attached files to share with more users.
Let's work together. We can help more users understand physics conceptually and enjoy the fun of learning physics!
