Question 86

To determine the period of oscillation of a mass suspended from a spring, a student times one complete vertical oscillation using a standard handheld stopwatch. Which modification to the experimental procedure will result in the greatest improvement in the accuracy of the measurement?

A

Timing the interval from the highest point to the lowest point of a single oscillation and multiplying the result by 2.

B

Measuring the time for 50 complete oscillations and dividing this total time by 50.

C

Replacing the stopwatch with a digital timer that records time to three decimal places.

D

Increasing the amplitude of the oscillation by pulling the mass down further before releasing it.
