A pendulum is a weight suspended from a string or wire that swings back and forth. The time it takes for a pendulum to make one complete swing is called its period. The period of a pendulum depends on its length and the acceleration due to gravity.
The experiment to determine the period of a pendulum is as follows:
Gather your materials. You will need a pendulum, a stopwatch, and a meter stick.
Set up the pendulum. Tie a weight to the end of a string and suspend it from a sturdy support. Make sure that the pendulum is free to swing back and forth without hitting anything.
Measure the length of the pendulum. Use the meter stick to measure the distance from the point of support to the center of the weight.
Start the stopwatch. Time how long it takes for the pendulum to make 10 complete swings.
Calculate the period of the pendulum. Divide the time for 10 swings by 10.
The period of the pendulum can be used to calculate the acceleration due to gravity. The following formula can be used:
T = 2π√(L/g)
Where:
T is the period of the pendulum
L is the length of the pendulum
g is the acceleration due to gravity
The acceleration due to gravity can be calculated by rearranging the formula as follows:
g = 4π^2(L/T^2)
The experiment to determine the period of a pendulum can be used to demonstrate the relationship between the length of a pendulum and its period. It can also be used to calculate the acceleration due to gravity.
