Explanation:
The period of a simple pendulum is:
T = 2π √(L/g)
where L is the length of the pendulum and g is the acceleration due to gravity.
The period of a pendulum can be decreased by decreasing the length of the pendulum or by moving the pendulum to a place with a higher gravity.
The period of a pendulum can be increased by increasing the length of the pendulum or by moving the pendulum to a place with a lower gravity.
