Physics Students Experiment With Pendulum
After measuring period, acceleration, and forces on the pendulum in The Naylor Building, AP Physics students used the information to calculate its length and the gravity at McDonogh. Then, armed with data, the group measured and calculated where to put small blocks that would be knocked down at regular intervals by the pendulum. Finally, on Thursday, February 12 the students positioned the blocks and waited with anticipation for the pendulum to knock them down one-at-a-time. The students estimated it would take until late Saturday evening for all the blocks to topple.
