How to Calculate and Solve for Period | Motion
Last Updated on March 27, 2024
The image above represents period. To calculate period, two essential parameters are needed and these parameters are length (l) and acceleration due to gravity (g).
The formula for calculating period:
T = 2π(√(l / g))
Where;
T = Period
l = Length
g = Acceleration due to gravity
Let’s solve an example;
Find the period when the length is 4 and the acceleration due to gravity is 9.8.
This implies that;
l = Length = 4
g = Acceleration due to gravity = 9.8
T = 2π(√(l / g))
So, T = 2π(√(4 / 9.8))
T = 2π(√(0.408))
T = 2π(0.6388)
Then, T = 6.28 x 0.6388
T = 4.014
Therefore, the period is 4.014 s.
Calculating the Length when the Period and the Acceleration due to Gravity is Given
l = (T / 2π)2 x g
Where;
l = Length
T = Period
g = Acceleration due to gravity
Let’s solve an example;
Find the length when the period is 28, and the acceleration due to gravity is 9.8.
This implies that;
T = Period = 28
g = Acceleration due to gravity = 9.8
l = (T / 2π)2 x g
l = (28 / 6.28)2 x 9.8
So, l = (4.458)2 x 9.8
l = 19.87 x 9.8
l = 194.7
Therefore, the length is 194.7.

Calculating the Acceleration due to Gravity when the Period and the Length are Given
g = l / (T / 2π)2
Where;
g = Acceleration due to gravity
T = Period
l = Length
Let’s solve an example;
Find the acceleration due to gravity when the period is 12 and length is 3.
This implies that;
T = Period = 12
l = Length = 3
g = l / (T / 2π)2
g = 3 / (12 / 6.28)2
Then, g = 3 / (1.91)2
g = 3 / 3.648
g = 0.82
Therefore, the acceleration due to gravity is 0.82.
