Movement simulation made easy. Spinning Hoop model displays the model of a bead moving along a hoop which is spinning about its vertical diameter with constant angular velocity ?. Friction is negligible. The simulation displays the motion of the bead as well as a plot of angle vs. time for the bead. The angular velocity of the hoop and the starting angle of the bead can be changed via sliders. You can modify this simulation if you have Ejs installed by right-clicking within the plot and selecting "Open Ejs Model" from the pop-up menu item.

A bead moves along a ring which is spinning about its vertical diameter with constant angular velocity. Friction is negligible. The unit time is (R/g)1/2, where R is the ring radius.
You can select and the initial angle (measured from the lowest ring point).
The point of view of the three-dimensional projection can be changed with the mouse (or the sliders).
Each whole image can be moved with the mouse while pressing Ctrl.
To change the zoom in the projections, press Shift when moving up or down the mouse pointer.
Put the mouse pointer over an element to get the corresponding tooltip.
