The period of a pendulum is the time it takes for one complete oscillation, which can be calculated using the formula:
T = 2π√(L/g)
Where:
T is the period,
L is the length of the pendulum, and
g is the acceleration due to gravity.
On Earth, the approximate value of g is 9.8 m/s^2.
Converting the length of the pendulum to meters:
L = 50 cm = 0.5 meters
Substituting the values into the formula, we have:
T = 2π√(0.5/9.8)
T ≈ 2π√(0.051)
T ≈ 2π * 0.226
T ≈ 1.421 seconds
Therefore, the period of the pendulum on Earth is approximately 1.421 seconds.
