The goal of this lab was to understand different aspects of newton’s laws. In the beginning we put 45g of metal rings in both of the bases to have a total of 50g in each side including the hanger’s mass which was 5g. We started to find out the m3 and we got 92g and 96g and the angle (Theta) for the m3 which was 77 and 250. While taking the measurements we couldn’t see the angles in between. Just we can see the half of any angle. Something important that we knew that when we add 2g the rope will move away from the center point. At the end by m3 and the angle we found Nm which was 0.388g and also N(theta) which was 9.397.
