Pendulum Length Formula
The following two example problems outline the steps and information needed to calculate the Pendulum Length.
PL = g / (4*pi^2*f^2)
- Where PL is the Pendulum Length (m)
- g is the acceleration due to gravity (m/s^2)
- f is the frequency (hz)
How to Calculate Pendulum Length?
The following example problems outline how to calculate Pendulum Length.
Example Problem #1:
- First, determine the acceleration due to gravity (m/s^2).
- The acceleration due to gravity (m/s^2) is given as: 9.81.
- Next, determine the frequency (hz).
- The frequency (hz) is provided as: 2.
- Finally, calculate the Pendulum Length using the equation above:
PL = g / (4*pi^2*f^2)
The values provided above are inserted into the equation below and computed.
PL = 9.81 / (4*pi^2*2^2) = .062 (m)
Example Problem #2:
For this problem, the variables required are provided below:
acceleration due to gravity (m/s^2) = 9.81
frequency (hz) = 3
Test your knowledge using the equation and check your answer with the calculator..
PL = g / (4*pi^2*f^2) = ?
