Question
How would the time period of a pendulum change if it were
taken to the Moon?Solution
The time period of a pendulum is given by the formula T = 2π√(L/g), where L is the length and g is the gravitational acceleration. Since the Moon's gravitational acceleration is approximately 1/6 of Earth's, the value of g decreases when a pendulum is taken to the Moon. With a smaller denominator in the formula, the time period increases proportionally to the square root of the reduction in gravity.
