Compare rolling theory to actual measurements

The table in the center of the room has a marked section which is L in length and rises h from end to end. We'll measure these values in class and write them on the board.

  1. What is the acceleration of an object which slides down the table without friction? Express this acceleration in two ways:
  2. How long should it take for an object to slide without friction down the table? Again, express this

There are seven objects we will actually send down this table. They are:

  1. For each type of object,

  2. rank the objects based on the time they should take to reach the bottom of the table: fastest at the top, slowest at the bottom of the list

Near the end of the class period, we will actually send each object down the table and measure the time it takes to reach the bottom. You can then compare your predictions with the actual measurements.
