WebbA pendulum in simple harmonic motion is called a simple pendulum. A pendulum has an object with a small mass, also known as the pendulum bob, which hangs from a light wire or string. The equilibrium position for a pendulum is where the angle θ is zero (that is, when the pendulum is hanging straight down). Webb2 feb. 2024 · The period of such a pendulum is about 2 seconds. To calculate this quantity, follow these steps: Find the value of your local acceleration due to gravity. A safe bet is g = 9.81 m/s². Substitute the value of g and l in the equation for the period of a pendulum: T = 2π × sqrt (L/g) =2π × sqrt (1/9.81) = 2.006.
