It can also be used to demonstrate the conversion between kinetic and potential energy and the effects of air friction or oscillation. A fish tank pump can be used as an air source. A bright and clear precision meter scale is added to each unit.
Horizontal Cast and Collision Tester
Here is a unique way to study horizontal and vertical motion, conservation of energy, and momentum. A track mounted to a vertical board directs one or two carts, casting them into a free fall. A brush projecting from the back side of the carts, marks the path of the cart as it falls. Weights can be added to the carts to study the effects of increased mass on momentum.
Maxwell's Wheel
Used for demonstrating momentum, conservation of energy and torque. This unit which is basically a large flywheel is suspended by two strong cords. These cords are wound around the shaft of the wheel and then released. The wheel will unwind as it falls but will wind itself back up as the momentum carries the wheel upward in the opposite direction. This oscillation process will continue for several moments as the wheel slowly lose momentums and travels less each time.
