Section 7: Energy in a Pendulum? In this section, you are going to investigate how energy is connected. Set the pendulum to the following initial conditions and let it swing. You will want to add the energy graph on the left side of the screen. Length Mass Gravity Friction 1 meter 1.5 kg Earth None I also suggest hit the plus sign a few times on the energy graph to zoom the graph in and make the bars bigger and easier to see. This does not make it have more energy just zooms it in. What happens to the total energy as you increase the angle? Where is there the most potential energy? As the pendulum is swinging, what happens to the energy? Where is there the maximum kinetic energy? Is the energy being conserved? Reset the pendulum to the initial conditions given at the beginning of this section, except this time, set the friction to the middle notch and use an angle of 20 degrees and let the pendulum swing. Observe and write what happens
