Lab ActivitiesThe motion of a golf ball projectile is analyzed in three ways:
In all three cases, the students check for the following things:
The experimental data can be taken in two ways: (1) using a Polaroid camera and a strobe light or (2) using an apple computer and a camera. In the first method the students determine the x and y coordinates of each image of the ball using cylinders and pins and the Polaroid photograph. In the second method, the students are given the coordinates by the computer. Results for g in either case lie within 3% of the accepted value. As an optional exercise, students can also be asked to analyze the motion of a styrofoam ball which is subjected to a wind in the negative xdirection.
