In this lecture, we will revisit the application of Newton's second law to a system of particles and derive some useful relationships expressing the conservation of angular momentum. Center of Mass Consider a system made up of n particles. A typical particle, i, has mass mi, and, at the instant considered, occupies the position Ti relative to a frame xyz. We can then define the center of mass, G, as the point

Introduction There is substantial dissatisfaction with the federal personal and corporate income tax systems. One possibility is to adopt a consumption tax whose base is actual consumption. Another possibility is a tax on wealth, whose base is accumulated saving
