Solution: In 60 seconds it makes 40 oscillations In 1 sec it makes = 40/60 = 2/3 oscillation So frequency = 2/3 per second = 0.67 Hz Time period = 1/frequency = 3/2 = 1.5 seconds 64) The time period of a simple pendulum is 2 s. 8.1 Pendulum experiments Activity 1 Your intuitive ideas To begin your investigation you will need to set up a simple pendulum as shown in the diagram. 525 768.9 627.2 896.7 743.3 766.7 678.3 766.7 729.4 562.2 715.6 743.3 743.3 998.9 You can vary friction and the strength of gravity. endobj g = 9.8 m/s2. Ze}jUcie[. >> /Type/Font (c) Frequency of a pendulum is related to its length by the following formula \begin{align*} f&=\frac{1}{2\pi}\sqrt{\frac{g}{\ell}} \\\\ 1.25&=\frac{1}{2\pi}\sqrt{\frac{9.8}{\ell}}\\\\ (2\pi\times 1.25)^2 &=\left(\sqrt{\frac{9.8}{\ell}}\right)^2 \\\\ \Rightarrow \ell&=\frac{9.8}{4\pi^2\times (1.25)^2} \\\\&=0.16\quad {\rm m}\end{align*} Thus, the length of this kind of pendulum is about 16 cm.
