3. template objects from lookang http://weelookang.blogspot.sg/2013/12/ejss-kinematics-model.html

The equation that model the motion of the ball is:

$  \frac{\delta y}{\delta t} = v_{y}$

$  \frac{\delta v_{y}}{\delta t} = a_{y}$

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:

1. recreate everything
2. made world view
3. made the 3 sliders
4. made drop-down menu for ease of productive learning ["user_defined","toss_up","free_fall"]
1. currently bouncing is not available if EJSS 5.0 beta has no event handler yet
5. checkboxes for $y$ vs t, $ v_{y}$ vs t and $ a_{y}$ vs t graphs
6. added markers to appears each second

enjoy!
