Original project [url=]Rolling with or without slipping[/url]

You can drag both end points of the plane to change the slope (angle)
If the friction coefficient is large enough, the circular object will rolling (without slipping) along the plane. (energy is conserved)
However, if the coefficient is too small, the object will slip along the plane and energy will be loss.
Plotting panel show traces for different energy:

Kinetic energy: (1/2) m v2
rotational energy: (1/2) I w2
potential energy: mgh

Can you identify all the traces?


You can drag cyan circle inside the rotating object, the trace for this small circle will be shown and the velocity vector(relative to object center ot ground) will be shown,too.
