When we discuss damping in Section 1.2, we will nd that the motion is somewhat sinusoidal, but with an important modication. To Find: Potential energy at extreme point = E P =? Both are suspended from small wires secured to the ceiling of a room. 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 $f=1/T$. 500 500 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 625 833.3 Use the pendulum to find the value of gg on planet X.

B ased on the above formula, can conclude the length of the rod (l) and the acceleration of gravity (g) impact the period of the simple pendulum.
