So far for our project, we are pretty confident about it because we have gotten to the minimum amount of transitions, so we know we are caught up and doing well. Inertia has effected our project because as we were trying to build our camel back, the marble wanted to continue going the same direction it was going, so it wouldn't work. We had to space apart the hills. What has been frustrating again was the loop. We had taken off the loop because every class it would have to be refixed because we would find it broken, so we replaced the loop with a track, which happened to be safer because we didn't have a track before. What we found has been working well every class was the beginning structure. It would never fail, and we like how we used cardboard rolls instead of just using a track, so that it would gain its kinetic energy, in other words, speed up.
