Part two of three. Designed to teach the content necessary for the new AP1 curriculum that will be replacing PreAP Physics in most districts, this presentation will include lecture, problems, hand-outs, and hands-on demos (from actual class labs). Participants will gain conceptual and mathematical understanding of torque and rotational energy (which is more complex than linear). Content: Basic Torque; moment arm (advanced torque); rotational energy (including advanced calculations).
