Going in Circles

My last homecoming. So fun but I cant believe its over. I hope everyone had a fun Halloween! I know I did! :) I was Belle, from Beauty and the Beast, wh0/what were you?
So, new concept of the week: rotation. I chose this picture because it shows rotation in the wheels and the actual bicycle going in circles. The wheels have a uniform circular motion. The bicycle ideally should have a uniform circular motion if I'm steering in a perfect circle. The period, or one revolution, of the wheels and the bike vary depending on how fast I'm pedaling. The centripetal acceleration of wheels are directed towards the center of the wheel, whereas the centripetal acceleration of the bicycle is directed towards the center of the circle I'm pedaling in. Remember last week when I explained how momentum worked? Momentum can also be applied here. As you can see Lumi is riding on the back of the bike with me. If we were going down a hill the momentum of the bike with Lumi and I would be greater than the momentum of the bike with just me because of the larger mass. Essentially, almost every physics concept I have explained to you can be applied to this picture: normal force and gravity, friction, work, etc.
