Question

can you think of an experiment to measure gravitational acceleration using simple pendulum? describe how you would analyze the data for that purpose?

Answer 1

Yes, We can measure gravitational acceleration g through an experiment in which we will measure the time period and the length of the pendulum.

We know that, Time period T = 2pi sqrt(L/g) where L is length

g = 4pi^2*L/T^2

We will measure time period by a stop watch by measuring time taken for N cycles and divide that time to get average time period T, and will measure length using meter scale.

After this the, the measured values of T and L can be put in above equation to find the value of g.
