52 Chapt. 5 Newton’s Laws and Dynamics I the object that start at two points used as pivot points and that go in the direction through the object that was downward when each of the points was the pivot point. The method fails if the two pivot points and the center of mass happen to be collinear.” a) What is an EMPIRICAL method for Fnding gravitational torque, Alex? b) What is a THEORETICAL method for Fnding gravitational torque, Alex? c) What is gravitational torque, Alex? d) What is a center of mass, Alex? e) What is an EMPIRICAL method for Fnding the center of mass of a rigid object, Alex? 005 qmult 00670 1 5 5 easy thinking: hanger center of mass 30. Where, roughly speaking, is the center of mass of a coat hanger? HINT: Imagine letting it hang from two di±erent free pivot points: this is called a Gedanken (thought) experiment in physics speak. If you arn’t in a test mise en sc` ene , you could actually do the experiment.
