Special pendulums

Newton's cradle

Dragging a ball introduces energy into the system. Observe how that energy passes from one ball to another.

Conical pendulum

In this simulation, the ball moves describing a circular horizontal path. Observe what happens as the period varies. Is there an equilibrium of forces?
