8105 Kit to study rolling motion

Additional kit for product code 8101.
Thanks to this kit it is possible to perform experiments on roto-translational motion.
The movement of bodies that roll on a plane is roto-translating as they translate while they rotate. However, their rotation does not take place around the axis passing through the center of gravity, but around the axis passing through the points of contact with the rolling plane.
