February 25, 2008 Physics for Scientists&Engineers 1 2 Systems of Particles and Systems of Particles and Extended Objects Extended Objects In our previous discussions this semester we have always treated the location of objects as a single point “A car is located at x = 5.5 m…” Of course, the car is not ALL at x =5.5 m The natural choice for the location of the car is the center of gravity of the car The center of gravity of an object is defined as the point in which we can imagine all of the mass of the object to be concentrated

February 25, 2008 Physics for Scientists&Engineers 1 3 The Center of Gravity The Center of Gravity We support an object such that the object stays balanced and does not rotate There are only two forces The force of gravity The force of the pin supporting the object Equilibrium = forces are such that Net force is zero => F g is attached directly below the supporting point Here, the center of gravity is marked with a red dot

February 25, 2008 Physics for Scientists&Engineers 1 4 Effect of the Center of Gravity Effect of the Center of Gravity Suppose we support the same object from the same pin, but the center of gravity is not directly below the support point The forces are the same
