Projectile off a table: range vs. height Basic scientific questions: 1. Is the range of a projectile (R) proportional to the height that a ball is lifted (h ) before it is rolled off of a table? 2. Does air make a difference? 3. Does rotational energy make a difference? Here is a basic picture of the idea of Lab 2: L. h h- R We will measure h, hy, and R and determine R as a function of h, and he. We will determine this function theoretically and then match it to our measurements through an uncertainty analysis very similar in the big picture of what we did in lab 1. But then we vary h, as described at the end of this document
