A pendulum of length l swings in a vertical plane. The string hits a peg placed at a distance h vertically below the point of suspension as shown. This makes the pendulum shorter for part of its motion.
Determine the time period T for the whole oscillation when h = 0.25 m.
l = 1.00 m
T = ...........................................
A student suggests that an approximate relationship between T and h is given by
Devise a plan to test the validity of the relationship using a graphical method.
Include the use of a stopwatch and any additional apparatus as required.
Another student suggests determining T by setting up a light gate attached to a data logger.
Discuss whether this modification would improve the investigation.
