Hello everybody, I need your help.
I want to do a simulation with EJS, to demonstrate the motion of a particle along arbitrary 3D curved path, and it generates a centrifugal force.
How to do?
Thank you!！

motion of a particle along arbitrary 3D curved path

The motion of a particle should follow physics law, it should not move in motion of a particle along arbitrary 3D curved path.

Normally, you need to provide the initial condition for the particle (x,y,z,vx,vy,vz)
and give evolution equation for the particle. (e.g. dx/dt=vx,dy/dt=vy,dz/dt=vz, dvz/dt=-g)
Then EJS will generate new simulation for your case.

You can check out many examples at this web site, find the one similar to your case, download EJS xml file (or download EJS jar file, run it and select open ejs model when right click).
And you will be able to find out how it was done by EJS.
Please starts with examples if you are a beginner for EJS.

Try to work on it with EJS and attached your ejs file when you encounter problem. We will try to check out your EJS source and help you!

Thank you, Professor Fu-Kwun Hwang. We previously had exchanges.
I want to customize the particle movement routes. Like the free driving spaceship.
If the Chinese forum to ask questions, you can promptly see it?
