Physics 30S. So today is Monday, October 2, and I
just wanted to give you a quick update about what we did and what is to come in
the next few class or so. We are studying Uniform Motion and Kinematics graphs.
We studied P/T and V/T graphs and the meanings of their slopes and area between
the line and the x-axis for V/T graphs.
On Tuesday
we will continue this discussion to include curved P/T graphs and introduce the
concept of acceleration and its associated graph. That will be followed by an
in-class assignment based on those items.
In relation
to the kinematics graphs, we will develop a few of the “Big Five” kinematics
equations that use t, v1 , v2, d, and a. Finally, we will use
our Big Five to solve problems that involve Uniform motion.
Graphs of Kinematics
Ok here are
three videos that match up with my lesson that I gave on Tuesday evening. Now
the concepts are all the same but you may see a very slight terminology change
or numerical change. They are 99% the same, though. Enjoy😊
Part 3 is omitted for now – Determining instantaneous
velocity
from a curved Position-Time graph. We’ll do that on Tuesday Oct. 3.
