Experiment of The Month
Bowling Ball Demonstration Pendulum
The Physics Club has begun a program of demonstrations for schools with the construction of a portable bowling ball pendulum. Physics major C. Harmon, and Rob Schwartz designed the black frame for the pendulum so that it will fold and fit into the back of a car. The do-not-try-this-at-home sequence is shown below. (The pictures were taken in the physics club
This is the physics major equivalent of walking on hot coals. Theory says that energy is conserved for the pendulum: i.e. that the energy is the sum of kinetic (1/2
If energy is conserved all the energy is now potential energy and the kinetic energy is zero. The velocity
This analysis fails catastrophically if you give the ball a push when you release it.
