I had to be away from school today in the morning but in the afternoon in Period 5 we started to learn about uniform circular motion. This is motion that travels along a circular path at a very constant rate. Even though the motion is uniform, the direction is constantly changing and this is caused by a centripetal acceleration. These accelerations are caused by centripetal forces. The key thing to know about centripetal forces is that they are caused by other forces, they do not exist on their own. We went through slides 60 - 66 and did examples 19, 20 and 21. Tomorrow we will finish the lesson with examples 22 and 23 and get a chance to work on Assignment 3.7. Period 1 will be doing what we learned today in Period 5.
Reminder that the lab report for Lab 3.1 is due tomorrow. Good luck with question #9.
