Angular Velocity, Angular Acceleration and Torque Introduction: In this lab we will use the gyroscope tool in the phyphox app to measure the angular velocity of the motion of an arm as it raises and lowers. Procedure: part 1: While lying on your back hold your phone straight upwards to the sky with screen facing you. (figure 1a). Press play on the gyroscope app. Now lower your arm straight down so that it almost hits the floor (figure 1b). Then raise it back up (do this in one motion as smoothly as you can). Repeat this motion twice again continuously and smoothly. Then press stop. When you look at the data, there will be three axis represented (x,y,z). Make note of the axis that has the greatest range of angular velocities (this is the axis around which you rotated. Transfer the data from this axis to a spreadsheet and graph the data from the axis with greatest range.
