2/15 Tamayo

Question of the day. What is the normal force at the top of a roller coaster loop if you are just on the verge of falling off?

The normal force would be close to zero. The normal force is greatest at the bottom of the loop and least at the top of the loop. The motion of the car keeps it from falling down so if it were on the verge of falling off the normal force would be nearing zero, once the car detaches from the track the normal force from the track can no longer act on the car.

Coats-Haan was not here for second period today in Physics. Mr. Ebersole led us in today’s activities. We first turned in Desperado Redesign, if we didn’t turn it in on Tuesday. If we turned it in on Tuesday then, it was in our folders. We then looked at page 139-140 Crazy Coasters. This lab is completed with the people at our tables. This lab is quite exciting. First we had to complete questions 1-6 then we were able to start the building process. This lab consists of creating a rollercoaster for a marble. We then have to calculate where the marble will land. We worked on this for the entire day and we will have tomorrow as well. The coasters will be tested on Tuesday after the long weekend. Mr. Ebersole did warn us that if we leave the room with the marble then we will lose a lot of points on this lab for our group. This concludes our activities today in second period Physics.
