1. Introduction. The purpose of this lab is to apply the scientific method to answer a simple
question. The lab will help you determine which variable will have an effect on the
period of the pendulum. The variables include the angle, length of the string
1. Introduction. The purpose of the experiment is to become more familiar with tools use
for electronic measurements. The oscilloscope uses a cathode ray tube to measure the
differences between voltages. The output looks like the teeth of a saw blade. The
1. Introduction. This experiment will study the trajectories of electron trajectories and the
way they are used in cathode ray tubes. The experiment will consider the electron to be a
point mass that follows Newtowns laws of motion. The deflection of an e
1. Introduction. This lab uses computer assistance to determine the measurement of g of a freefalling body. G is acceleration due to gravity. The determined value will be used for later
experiments. The graph of velocity time graphs slope is g.
