The first lab was the air track. We used two gliders to and tested inelastic collisions. The second lab was a computer simulated one where we tested inelastic and elastic collisions and the third lab was the impulse lab where we measured the impulse with a cart. For the air track lab we did not get very good results because the momentum before the collision didn’t equal the momentum after the collusion. Most of our deviations were big. For the computer lab we had good results where in each case the momentum before the collision equaled the momentum after the collision and for the impulse lab, our data wasn’t good because the impulse didn’t equal the change in momentum. For the air track lab our smallest error was 140%. The error was so big because the photogates may have not been set properly or we didn’t use the equipment right. For the impulse lab our smallest error was 50%. Causes of the error may have been not setting the motion detector right, the spring might not have been straight or the car didn’t roll good. I think that the air track and the impulse lab weren’t very good because our values were different from what we should have had. Bibliography: Word Count: 221
