Yung hangs a mass from a rod, sets the pendulum in simple harmonic motion, and determines the period of the pendulum. how could yung decrease the period of the pendulum?

In all trials, the magnitude of the final velocity for g1 + g2 was less than the magnitude of any initial velocity. as mass increased, what happened to the velocity? the velocity decreased. the velocity increased. the velocity of g1 + g2 could not be measured. the velocity was not affected by the mass increase.
