Warm Up:
1. Propose an explanation for why this
velocity graph is so scattered looking.
2. What five variables should you look for
in kinematics problems?
Today:
 I finished reviewing and making comments on the video analyses
(A5/6,
A7/8)
. If you have a yellow cell, you must redo whatever is yellow.
Otherwise, making corrections is not mandatory.
 Completion of the video analysis is required, unlike ordinary
homework. If you have not submitted analysis videos and
graphs, you may still do it for credit.

total), 14multiple choice (14 points), 1 unit conversion problem
(2pts), 5 onepart problems (20pts), 1 extended problem with 6 parts
(12 pts). 52 points in all, worth at least 80% of your grade
as of Thursday.
 Topics on the test: What it can mean to have different
combinations acceleration (+,, or 0) and velocity (+,, or 0);
graphing; freefall; unit conversion; problems (identifying
variables and applying correct formulas), including proper units,
showing work for partial credit, formulas for average velocity and
acceleration
 What to study: notes, homeworks (including Mr.
Pennington's old test), practice test. Video analysis will
not be on the

a circular track. The car's speedometer stays on exactly 100mph
the whole time.
Describe what happens to each of the following
as the car makes one revolution around the track:
a) the car's speed b) the car's velocity c) the
car's acceleration.
2. All of the speed calculations in the
screenshot on the right (blue) are
slightly off, and the last speed calculation (red)
is really, really off. Why?

A ball is launched directly upward from the Earth's surface.
The ball returns to Earth and hits the ground after a time of 10
seconds. Assuming no air resistance and g≈10m/s^{2},
fill in the values in the diagram on the right.

Class
4.5 Monday,
9/10/18
Warm Up:
The symbol "g" usually represents the absolute value of the acceleration of
gravity near Earth's surface (in the absence of air resistance). The approximate value of g is 9.8m/s^{2}.
For the sake of simplicity, use g = 10m/s^{2} to complete
the motion graphs for an object with v_{0} = 20m/s and y_{0}
= 0m.
[Ignore air resistance.]

 Video Analysis is Due on Wednesday
 Complete your row of your class' spreadsheet (A5/6,
A7/8).
 Make sure that everything (videos and spreadsheets) are
shared with "anyone with a link."
 Fix your motion graphs so that they
correctly represent the motion from
your video. In cases where your video was
rotated sideways in Logger Pro, you may use formulas to fix the
data or you may resolve the confusion with creative yaxis
labeling. For example, if your video shows a dropped ball,
but the video is rotated counterclockwise, so that the ball
seems to accelerate positively to the right, you may label your
velocity graph y axis with the following statement "speed in the
direction of the ground (meters)." For objects with
diagonal motion, you will need to specify which component of the
object's motion is being represented, so your y axis might be
labeled "upward speed," "downward speed," "rightward speed," or
"leftward speed." If you want a challenge, you could use
formulas to calculate the actual diagonal speed based on the x
and y velocities, using the pythagorean theorem.

Class
4 Friday,

Warm Up:
1. For letter a, on the right describe what an object could be doing
in order to have both positive velocity and positive acceleration.
2. Do the same for the rest of the letters.

Use the Logger Pro (stationary camera) method first,
following the
Video Analysis Directions.
You should use Logger Pro first because you probably will
not have access to Logger Pro at home. Quicktime
player, on the other hand, is fairly easy and free to
download.
 Analyze another
video without using QuickTime (motion along a ruler). To make your task easier, feel free
to copy these spreadsheetsand modify them to meet your needs (Logger

1. Assuming that the man in the picture is 2m tall, and
the frame rate of the camera was 30 frames per second, what were the approximate
maximum and minimum speeds of the object?
2. Based on your answers, do you think the
assumption of 30 frames per second was too loww, too high, or about
right?
3. If you could travel in time, and you found
yourself in the infinite loop of acceleration changes shown below...
a) what might your velocity and position graphs look like?, and b)
would you ever find yourself in the same location as another past
self? If so, show how this could occur.
