In the following, a couple of problems about simple pendulum in various situations is presented. A simple pendulum of length 1 m has a mass of 10 g and oscillates freely with an amplitude of 2 cm. Dividing this time into the number of seconds in 30days gives us the number of seconds counted by our pendulum in its new location. By how method we can speed up the motion of this pendulum?
Modelling of The Simple Pendulum and It Is Numerical Solution What is the generally accepted value for gravity where the students conducted their experiment? g = 9.8 m/s2. (Take $g=10 m/s^2$), Solution: the frequency of a pendulum is found by the following formula \begin{align*} f&=\frac{1}{2\pi}\sqrt{\frac{g}{\ell}}\\\\ 0.5 &=\frac{1}{2\pi}\sqrt{\frac{10}{\ell}} \\\\ (2\pi\times 0.5)^2 &=\left(\sqrt{\frac{10}{\ell}}\right)^2\\\\ \Rightarrow \ell&=\frac{10}{4\pi^2\times 0.25}\\\\&=1\quad {\rm m}\end{align*}. 460.7 580.4 896 722.6 1020.4 843.3 806.2 673.6 835.7 800.2 646.2 618.6 718.8 618.8 1. xZ[o6~G XuX\IQ9h_sEIEZBW4(!}wbSL0!` eIo`9vEjshTv=>G+|13]jkgQaw^eh5I'oEtW;`;lH}d{|F|^+~wXE\DjQaiNZf>_6#.Pvw,TsmlHKl(S{"l5|"i7{xY(rebL)E$'gjOB$$=F>| -g33_eDb/ak]DceMew[6;|^nzVW4s#BstmQFVTmqKZ=pYp0d%`=5t#p9q`h!wi 6i-z,Y(Hx8B!}sWDy3#EF-U]QFDTrKDPD72mF.

Thus, the period is \[T=\frac{1}{f}=\frac{1}{1.25\,{\rm Hz}}=0.8\,{\rm s}\] Solution: The period and length of a pendulum are related as below \begin{align*} T&=2\pi\sqrt{\frac{\ell}{g}} \\\\3&=2\pi\sqrt{\frac{\ell}{9.8}}\\\\\frac{3}{2\pi}&=\sqrt{\frac{\ell}{9.8}} \\\\\frac{9}{4\pi^2}&=\frac{\ell}{9.8}\\\\\Rightarrow \ell&=9.8\times\left(\frac{9}{4\pi^2}\right)\\\\&=2.23\quad{\rm m}\end{align*} The frequency and periods of oscillations in a simple pendulum are related as $f=1/T$.
