Physics 100: Torque and Equilibrium of Rigid Bodies

Comprehensive course covering the topics of torque, equilibrium and center of mass and stability.

This course covers torque, center of mass, rigid bodies in equilibrium, and the stability of objects.   The course is a mix of lectures and problem solving tutorials.   Students will learn to how to calculate torque, how to evaluate the center of mass of systems of particles and objects with uniform density.    I will teach you how to approach problems and help you develop your own problem solving strategies to become a better problem solver.
