In class, we learned how to calculate the details of energy related to our pendulum.
Mass = 6kg
Initial height = 1m
Using the mass & height measurements of our pendulum, it looks like the energy stored is: 58.8 Jules.
Assuming we allowed the Pendulum to run for a full two minutes, the average power at which the initial energy was transferred to the environment is 0.49 watts.
And if we were able to use all the initial potential energy in just 10 seconds, we would have 5.88 watts. Interestingly, an iPhone is charged at 5 watts!
