🎡 Animated Pendulum
The pendulum moves to and fro about its mean position.
Bob: The heavy object tied to the string.
Length: Distance from pivot to the center of bob.
Time Period: Time taken for one oscillation.
Frequency: Number of oscillations per second.
T = 2π√(L/g)

🧠 Higher Order Thinking Questions
1. Why does a longer pendulum take more time?
Because the time period increases with the length of the pendulum.
2. Why does mass not affect the time period?
Because mass is not present in the formula of time period.
3. Why does the pendulum stop after some time?
It stops due to air resistance and friction at the support.
4. Why are small oscillations preferred?
Because for small oscillations the time period remains nearly constant.
5. Why are pendulum clocks accurate?
Because the pendulum has a nearly constant time period for small oscillations.
❓ FAQ
What is a simple pendulum?
A simple pendulum is a small heavy bob suspended from a fixed point by a light inextensible string so that it can oscillate freely.
What is the time period of a pendulum?
The time period is the time taken by the pendulum to complete one full oscillation.
Which factor affects the time period of a simple pendulum?
The time period mainly depends on the length of the pendulum and the acceleration due to gravity.
Does the mass of the bob affect the time period?
No, the mass of the bob does not affect the time period of a simple pendulum.
What is a second pendulum?
A second pendulum is a pendulum whose time period is 2 seconds.
