Machines and Tools (Part 2)
Which pulley system will give us a whale of a good time? Teams compare the theoretical and actual mechanical advantages of different pulley systems. They then form a recommendation for how to move a whale from an aquarium back to the ocean.
Exploratorium
Momentum Machine
If you have a rotating office chair in your classroom, you can have physics pupils participate in this simple, yet effective demonstration of angular momentum. One partner sits in the chair, arms outstretched, holding heavy weights. The...
