Experiment 1Procedure:In a single video, track the motion of five points (five different radii) for at least half a revolution. The easiest way would be to go through the video taking data five times. Set your origin at the center of rotation. Note the radius of the five different points.Report:Using the formula on the first page of the lab manual, θ= tan-1(y/x) convert your position data into angular data in excel. Plot the angle versus time, fit a linear trendline, and the slope will be the angular velocity, ϖ. For each of the five points, calculate the linear velocity, v = ϖr, and the centripetal acceleration. A table would be a good way of presenting these results.Experiment 2Procedure:In this experiment, you’re going to have the cart moving with a constant velocity, which means the disc that it is attached to will be rotating with a constant angular velocity. You’ll need to track the motion of a point on the edge of the disc and the cart. Set your
