ME17.3 Long Pendulum Hanging from Ceiling
This is mainly used for conservation of energy. This pendulum suspended from the ceiling with a long rope already attached to the first pillar on the right facing the class. A student volunteer feels the weight of the ball, then attaches it to the rope. He stands by the pillar and puts the ball to his nose. Then he lets go and remains in place. From his point of view, the ball will hit him in the face, but conservation of energy says that the ball will go no closer to his nose than it was when he let go.
