Can a pendulum clock be used in an earth-satellite?

No, a pendulum cannot be used in an earth-satellite because in space, the gravity g is zero. Due to this it cannot execute simple harmonic motion. Hence, it cannot be used as a clock.


g=0, time period T will be infinite. Hence, pendulum cannot act as clock.

A hollow sphere filled with water is used as the bob of a pendulum Assume that the equation for simple pendulum is valid with the distance between the point of suspension and centre of mass of the bob acting as the effective length of the pendulum. If water slowly leaks out of the bob, how will the time period vary?
