This EjsS Free Fall was developed using the Easy Java/JavaScript Simulations (EjsS) version 5. Although EjsS is a Java program, it can create stand alone JavaScript programs that run in almost any PC or tablet.

changes made:

recreate everything
made world view
made the 3 sliders
made drop-down menu for ease of productive learning ["user_defined","toss_up","free_fall"]

currently bouncing is not available if EJSS 5.0 beta has no event handler yet

checkboxes for y vs t, vy vs t and ay vs t graphs
added markers to appears each second

enjoy!
