March+6th+-+TAYLS

To get the velocity you do 2 times pie times the radius divided by (time divided by 20). **
 * Today’s class began with a mild 10-point quiz on circular and rotational motion, specifically tangential speed, frequency and period. After all quizzes were complete and handed in, the class was instructed to take out their Centripetal Forces Lab: Swingin’ Nephews. The original twirler, Liz, then picked a second twirler. The chosen one was Dan. Clad in some spiffy goggles and a navy and maroon plaid shirt, Dan completed his duty with pride. The time recorded was 11.59 s and the force reading was 1.05 N.Donnell was picked next by Dan even though he was quite unenthused with the whole operation. As expected, Donnell botched the data by forgetting to look at the force scale during his swinging. Smooth. He then attempted a second time. The time was 10.69 s after Walter took over due to Donnell’s incapability. The force reading was 1.47 N. I then was called up by Walter but was then as equally incapable as Donnell but more optimistic about the situation. I PICK MOYO! He was pretty skilled at making the rotations. The time recorded in the fourth block was 9.17 s and the force was 2.20 N. Moyo chose little Ricky, dressed in a royal blue North Face and some comfy, grey sweats. The time was 8.58 s and the force was 2.63 N. Lindsey was the final spinner but couldn’t quite achieve the correct velocity. Pablo was elected…lets see if he can handle the challenge. Nope. I gave it a whirl and failed. MOYOS UP! He’s kinda beastly so he can probably do it. The time was 5.87 s and the force was 4.45 N. He manhandled it.

Looks like we still have some more information to record. Onward to the next chart! Emilia clocks in for her round. Time – 10.63 s and radius - .4175 m. Miles then took his turn and Scott did as well. If you wish to get the rest of the chart information, ask a neighbor to borrow theirs. Until next time, this is Tayls checkin’ out:) **
