This following applet is Satellite motion
Created by prof Hwang Modified by Ahmed
Original project Satellite motion

You will find two simulations for satellite motion due to the gravitation force between satellite and massive object(center one with cyan color).
Which one is the correct simulation? The one will rotate or another one which does not rotate?

You can pause the simulation. Change the location or velocity of the satellite when velocity vector is visiable, then press 'play' button again. Enjoy it!

Embed a running copy of this simulation

Embed a running copy link(show simulation in a popuped window)

• 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!

the show force seems to be not pointing towards the centre of the motion, please check your equation to see if the physics is correct

It should be fine if you change the numerical method to Ringe-Kutta 4th order method.
