Many principles of mechanics can be nicely demonstrated with the Blackboard Mechanics Set. Among them are:
Friction blocks on inclined planes | |
Statics of inclined planes | |
Levers and center of mass | |
Vector addition of forces | |
Pulley systems | |
Pendula and springs |
A description book of various experiments is available.
Terminal velocity is shown by dropping a ping-pong ball (with denser balls, if desired) from a platform and illuminating its fall with a strobe light. (See Three Balls Falling [1])
