This applet simulate many particles slide down at different angle.

How does this show the concept of Energy conservation: potential/kinetic energy ?

with some explanation i should be able to make creative common it into something that schools can get students to explore themselves  :)

For your consideration  ;)

The blue curves show blue(i)=(1/2)m*vi2/(m*g), while black curves are black(i)=yi.
For each pair of curves, you will find blue(i)+black(i)=constant.
So it is corresponds to conservation of energy.
You can also draw curves for (1/2)m*vi2 and m*g*yi, and you will find the sum are the same for all the curves.

What I did was just change the unit to be (m*g). So I draw (1/2)m*vi2/(m*g) and yi-- vertical position of particle.
