Calculating the Period of a Pendulum on Mars

In this video, I walk you through problem 27 from Chapter 11 of Giancoli Physics, focusing on the period of a pendulum on Mars compared to Earth. We start with the given period of 1.85 seconds on Earth and the acceleration of gravity on Mars, which is about 0.37 times that of Earth. I guide you through the necessary calculations and the relationships between the periods and gravitational forces. Please pause the video to work through the problem before we compare notes at the end. Giancoli Physics, AP Edition, 7th Edition, Chapter 11, Problem 27
