Figure 1: Materials for lab (left): Pendulum apparatus, PASCO photogate, and launcher. First step is to measure length of pendulum (right) from pivot to center of mass.
Figure 2: Tape down photogate to apparatus (left), then clamp down apparatus to table (middle). Then, prime ball in launcher (right). Take required measurements for speed of ball moving through gates without going into the pendulum catcher.
Figure 3: When leaunching ball into pendulum, it will lock in the highest position. Measure initial height that pendulum started, and final height where pendulum stops. Read angle at the top of pendulum. True measurement is closer to the left side of the red marker.
