The equation that model the motion of the car is:

$  \frac{\delta x}{\delta t} = v$

$  \frac{\delta v}{\delta t} = a$

This EjsS  Kinematics Problem Package 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","at_rest","uniform_motion_=_1","uniform_motion_=_2","uniform_motion_=_-1","uniform_motion_=_-2","simple_acceleration","simple_deceleration","negative_acceleration","positive_deceleration"]
1. at_rest x=0;   v=0;   a=0;
2. uniform_motion_=_1 x=0;   v=1;   a=0;
3. uniform_motion_=_2 x=0;   v=2;   a=0;
4. uniform_motion_=_-1 x=0;   v=-1;   a=0;
5. uniform_motion_=_-2 x=0;   v=-2;   a=0;
6. simple_acceleration x=0;   v=0;   a=1;
7. simple_deceleration  x=0;   v=5;   a=-1; true only for v < 0
8. negative_acceleration x=0;   v=0;   a=-1;
9. positive_deceleration x=0;   v=-4;   a=1; true only for v > 0
5. checkboxes for x vs t, v vs t and a vs t graphs
6. added markers to appears each second

enjoy!
