We started off the class with a review on angular and linear speed.
The example of a bicycle wheel was used.
A 29 inch wheel at 2 revolutions a second.
Linear Speed?
Take into account that distance = speed * time

182.2 (inches/second) = 10.35 mph

note: Stoichiometry can take care of all unit conversion before you really start the problem:


Angular Speed?


Additionally, it was proven that: radius * angular speed = linear speed, which will be useful for problems in the future.

We finished up class with the first Unit 4 quiz in Ms. Ferlauto’s room.
