Find the period and frequency of oscillations of a mathematical pendulum whose thread length is 0.141 m.

univerkov | August 16, 2021 | education

Problem data: l (length of the thread of the mathematical pendulum) = 0.141 m.

Reference values: g (acceleration due to gravity) = 9.81 m / s2.

1) The period of oscillation of the mathematical pendulum: T = 2Π * √ (l / g) = 2 * 3.14 * √ (0.141 / 9.8) = 0.753 s.

2) The oscillation frequency of the mathematical pendulum: ν = 1 / T = 1 / 0.753 = 1.33 Hz.

Answer: The oscillation period is 0.753 s, and the oscillation frequency is 1.33 Hz.
