How to find "g" using a simple pendulum? We just started physics in grade 11. I have no idea of how to find g using a pendulum. This a lab we will have to do soon in the near future I am here to do some research before we have to do the lab. I've done some other research on the net, and i came up with no solution. What is the equation for to determine g from a pendulum? What are the variables? Thank you!
