Course Objectives: 1. Define Torque and Newton's laws of rotational motion. 2. Utilize torque and equations of rotational motion to solve statics and dynamics problems. Torque: Activity #1: The first activity will help us better understand our own sense of balance and center of mass. 1. First, stand up straight in the center of the room with nothing around you, or have a lab assistance do this. Next bend at the waist and touch your toes, or ankles if you are not quite as flexible as you used to be. Do not bend your knees during this experiment. Write down any observations here, and include a photo/sketch of you or the assistant touching the ground/feet. Annotate the photo/sketch with an estimate of the location of your center of mass. 2. You will have to be very careful in this experiment. Stand with your back and the heels of your feet against a wall (or a lab assistant can do this). SLOWLY, try to reach down and touch the floor/feet/ankles, without bending your knees. The moment you start to fall forward, be sure to catch yourself, so you do not get hurt! Write down any observations, noting the similarities and differences to #1. Include a photo or sketch of the moment right before falling. Annotate this photo/sketch with an estimate of the location of your center of mass. Describe how this center of mass differs from #1
