FAQs on Simple Pendulum Video Lecture - Class 11

1. What is a simple pendulum?
Ans. A simple pendulum is a weight suspended from a pivot point that can freely swing back and forth. It consists of a mass (bob) attached to a string or rod, and when displaced from its equilibrium position, it oscillates due to the force of gravity.
2. How does the length of a simple pendulum affect its period?
Ans. The length of a simple pendulum directly affects its period, which is the time taken for one complete oscillation. The longer the length of the pendulum, the longer the period. This relationship is described by the formula T = 2π√(L/g), where T is the period, L is the length of the pendulum, and g is the acceleration due to gravity.
3. What factors affect the period of a simple pendulum?
Ans. The period of a simple pendulum is influenced by several factors. These include the length of the pendulum, the mass of the bob, and the acceleration due to gravity. Additionally, the amplitude (maximum displacement from the equilibrium position) and the angle of release can also have minor effects on the period.
4. What is the relationship between the period and frequency of a simple pendulum?
Ans. The period and frequency of a simple pendulum are inversely related. The period is the time taken for one complete oscillation, while the frequency is the number of oscillations per unit time. The relationship between them is given by the formula f = 1/T, where f is the frequency and T is the period.
5. Can the mass of the bob affect the period of a simple pendulum?
Ans. The mass of the bob does not affect the period of a simple pendulum. The period solely depends on the length of the pendulum and the acceleration due to gravity. However, the mass can affect the amplitude of the pendulum's swing and the amount of energy transferred during each oscillation.
