Question

Q.Take a ball or a stone and wrap some cloth around it.
Now, tie it to the end of a thread of a definite length
(say 1 metre) and hang it somewhere from the ceiling,
This will be your little pendulum. Push it with
considerable force and measure the oscillation time
period with your smartwatch. You can start by taking
the period as 5 or 10 oscillations to avoid any mistake.
Now with the help of formula, T = 21/g
Where, T = Time period measured in seconds
I = length of the pendulum string
g = gravitational constant (value is 9.8 m/s2)
