Place the cart at least 0.2 m away from the motion detector. Click the collect button to begin taking data. When you hear the motion detector s art clicking, give the force probe a short pull in the direction away from the motion sensor), and then let the cart move freely. While you are collecting data, keep your hand and the cable out of the way or the motion sensor will detect those instead of the cart. Repeat the measurement as needed. Sketch the velocity and force graphs
