Question

13. When simple pendulum swings, which of the following quantity does not become zero
throughout the oscillation:
a. mass of pendulum
b. momentum of pendulum
c. acceleration of pendulum
d. velocity of pendulum

Answer 1

When simple pendulum swings, which of the following quantity does not become zero

------- (a) mass of pendulum.

Reason:

• At extreme position of SHM , velocity of particle becomes zero.
• Momentum = m×v ; so momentum also becomes zero at extremes.
• At mean position SHM has maxi velocity and Zero acceleration.
• So momentum, velocity, acceleration all become zero in specific position during SHM except mass.
