The Pendulum
1.) If you were to time a single oscillation, where would your main sources of error arise?
The mass spring is a common measurement device that can provide inaccuracies when timing a single
oscillation

Questions:
1.) Why is the spillway from the inflow cup needed?
The spillway is needed for the controlled release of flows. This spillway establishes a constant flow and
prevents the water level from getting too high.
