This is my first simulation. Hi my name is Andres Garcia, Senior High school student from mexico and i did this simulation as a physics project.
I used Andrew Duffy simulation to begin, because i didn't know how to use EJS, so i modify it putting Initial velocity, Gravity, Mass, Final Velocity, Displacement, Work , Force and Acceleration.

Thanks to Loo Kang For the help and support and Andrew Duffy for the first simulation. :)
