Question

How can u change the time period of a simple pendulum?

Answer 1

u can change the time period of a simple pendulum by increasing on decreasing the degree of angle

Answer 2

Time period of a simple pendulum is
$2\pi \sqrt{ \frac{l}{g} }$
Since it clearly depends upon the length , l of the pendulum , we can change the time period of the pendulum by changing its length

But we can't change the time period of the pendulum by changing g(gravitational field) since it is a constant (for small heights)
