The first class of the day for twenty-two people is physics. They were going to learn how to find the velocity of an object that is in a circular motion, but first there were a few activities that they had to do first. First, Mr. Manning showed a video of the crazy scientist dude who swing a ball in a circular motion and let it go to see in which direction is the ball going to go. It turned out that the ball traveled in the circular motion but then went straight as it one fourth of the way. Next on the calendar is the daily question of the day. The question was “ The guests are sitting at a large table in a Chinese restaurant use a revolving tray, a Lazy Susan, to share the dishes. How does the lazy Susan motion different from the passing dessert cart?” the answers were that the lazy Susan was going the circular motion, there were more chance that the dishes would fall off. Plus there were no displacement on the lazy Susan. Next activity is the Farris Wheel with Mr. Manning. By doing this activity we learned about the velocity of an object in a cicular motion. The equation is that the circumference of the motion divide by its time. The tme could be call period which is the time for one rotation. Another equation is for the rotational speed. It is measure in rotation per second. Which is the number of rotations per time.
