Here are a few questions you should be able to answer off the top of your head:

•  Hockey coaches, wearing street shoes, go pretty slowly when they're walking across the ice. Is this because they're taking short steps or stepping at a low frequency? Is this necessary?

•  Several objects roll down a hill. One is a bowling ball, one is a solid cylinder, and one is a hollow cylinder. Assuming they all roll without slipping and that they start at the same time, in what order do they arrive at the bottom of the hill?

•  A 1 kg weight hangs from a 1 meter long string. 20 cm below the nail from which the string hangs protrudes a second nail. The weight is pulled to the right, so that the string makes an angle of 30 degrees with the vertical, and the weight is released. Describe fully the subsequent motion of the weight. (Yes, the string catches on the second nail.)

•  Your cousin puts his car into neutral and coasts down a hill that makes an angle of 3 degrees with the horizontal. The car reaches a terminal speed of 30 miles per hour. If your cousin does the same on a hill that makes an angle of 5 degrees with the horizontal, what will be the new terminal speed?

•  You have 10 identical physics books. You stack them near the right edge of the table, possibly staggering them. Is it possible to stack them so that the top book lies entirely to the right of the table? Is it possible to do this by staggering them equal amounts, so that they look like an orderly staircase?

•  Given a simple pendulum whose period is 2 seconds, what happens to this period if the pendulum is allowed to swing in an elliptical path?

•  Cars tilt when going around a corner. Which way do they tilt, and why?

•  A pendulum bob, mass m, is released from a height h. When it reaches the bottom of its arc, it strikes a piece of putty also of mass m. The putty sticks to the pendulum bob. How high does this conglomerate rise?

•  A thin soap film on a piece of glass shows a variety of colors. If this film can be lifted from the glass, will the colors change?

• A charge Q sits at the center of a cube of side a. At each of the corners but one sits a charge q. What is the Coulomb force on the charge Q?

• A charge Q sits at the corner of a cube of side a. What is the electric flux through this cube?
