At the extremities of the pendulum's swing, the sand leaving the bob could exert a force on the bob. Provided that this force is negligible and also, provided the mass of the bob (with or without the sand) is large compared with the rest of the pendulum, the time period should not be affected.
The length of the pendulum is measured from the pendulum's point of suspension to the center of mass of its bob. Its amplitude is the string's angular displacement from its vertical or its equilibrium position.
When the elevator starts moving down, the time period increases. But when the elevator is descending at a constant velocity, the time period returns to its normal.
The time of a period doesn't depend on the mass of the Bob(that'll be a mass spring system) It also doesn't depend on Friction..
The period of a pendulum is totally un-affected by the mass of the bob.The time period of pendulum is given by the eqn.T=2*PIE*(l/g)1/2 ;l is the length of pendulum;g is the acceleration due to gravity.'l' is the length from the centre of suspension to the centre of gravity the bob.ie.the length of the pendulum depends on the centre of gravity of the bob,and hence the distribution of mass of the bob.
