PHYS 1060-001: How Things Work

• 1. The air pucks (again). 2. A bowling ball and a base ball (Here I do not want the bowling ball suspended from the ceiling the way Lou had it, I just want one on the table. Maybe also a tennis ball. 3. Two full and two empty soda cans. Also, could we get an overhead camera on them. I would like to literally blow on them so that the student’s can see the difference in how they move, but it might be subtle if they cannot see them from the top. 4. Do we still have that giant air track thing? If so, I would love to have it. If not, a regular sized air track would be fine, ... Note, I do NOT need the Razor Scooter again, ... 2018-01-19 00:00:00 • 1. Razor Scooter and Stand 2. 2 baseballs 3. Red bowling ball 4. Bouncy ball (large) 5. Tennis ball 6. Two full soda cans 7.

• 1. Van de Graaf with pom pom and knitting needle. perhaps also the plastic stool and the mirror, since the humidity is much lower today, and you replaced the belt. 2. The Wimshurst machine (we use 10kV supply) and the electric field demo, the one with shredded felt. For this, I am interested particularly in two types of shapes, the flat electrodes and the small round electrodes. I would like to show parallel capacitor fields, dipole field, and most important of all, the field between the small round electrode and a flat electrode.

I am including a screen shot (taken from Lou’s video) that shows the one I would like to have. 5. Barkhausen Effect demo 6. Next, I would like to visualize some magnetic fields using iron filings. I would like to do two cases: 1) a bar magnet, and also 2) a kitchen refrigerator magnet. I couldn’t find the exact demo to ask for, but I saw Lou do this. He did one that involved a fluid. I would just prefer to do it with either a piece of paper or perhaps a thin piece of plastic if that is possible. I am hoping that these props weren’t things he brought with him! 6.
