Measurement of time

 Product No: P0998200

Principle

The student should count the oscillations of a pendulum while timing them with the aid of a stopwatch. To determine the dependence of the oscillation period on  the length of the pendulum is shortened by 50% in the second part of the experiment.

The oscillation period of a pendulum is

T=2??l/g

where l  = Pendulum length and  g  = 9.81 m/s2 (acceleration of gravity).

Task

How rapidly does a pendulum oscillate?

Count the oscillations of a pendulum while timing them with the aid of a stopwatch. To determine the dependence of the oscillation period on the pendulum's length the length is shortened by 50 % in the second part of the experiment.
