SUMMARY
The motion of a pendulum in an accelerating elevator is influenced by the change in effective gravitational force. When the elevator accelerates upward, the apparent gravitational acceleration increases due to the addition of inertial force, resulting in a modified period of the pendulum. The formula for the period of a pendulum, T = 2π(√(L/g)), indicates that as g increases, the period T decreases. Thus, the period of the pendulum shortens when the elevator moves upward with constant acceleration.
