We suppose a rod is attached by its end to some pivot, and is allowed to fall from a horizontal position. As this occurs, the rod loses gravitational potential energy (∆UG), say 10J, thus gaining the same amount in kinetic energy. To which the form of energy to which this ∆UG is converted?
- ∆UG=Kcm
- ∆UG=Krot
- ∆UG=Kcm+Krot
Explain your reasoning, please!

2) A 1-meter rod of uniform density and mass 1 kilogram is attached at its upper end to a pivot, from which it can freely swing (like a pendulum). If it swings 30 degrees to the side, by how much has its gravitational potential energy changed. 5) Anticipating the effects of friction, air resistance, and the nature of the collision between the ball and the pendulum, rank from greatest to smallest: the final gravitational potential energy of the pendulum, the...

Pivoted Rod with Unequal Masses (Figure 1) A thin rod of mass mr and length 2L is allowed to pivot freely about its center, as shown in the diagram. A small sphere of mass m1 is attached to the left end of the rod, and a small sphere of mass m2 is attached to the right end. The spheres are small enough that they can be considered point particles. The gravitational force acts downward, with the magnitude of the gravitational acceleration...

1. A thin rod of mass M and length d hangs vertically from a frictionless pivot attached to one end. A piece of clay of mass m moving horizontally at a speed v hits the rod a distance x from the pivot and sticks to it. Discussion Questions: (In the first 5-10 min a random group will be selected to explain.) • What “type” of collision is happening? What is and is not conserved? • Consider the analogous linear momentum...
