A head on elastic collision between an object with mass M and an object with mass 3M traveling with equal speeds results in all the kinetic energy of the system being transferred to the smaller mass. In this demonstration we try to follow this arrangement to produce a...

A pendulum is constructed from a 1.0-kg mass suspended from the ceiling, with a length of strong string long enough so that, when pulled about 40o from the vertical, the mass comes to nose level. The pendulum will be released from this position. The demonstrator is to...
