Physics 130 Lecture-related material
Note that all PDF files are password protected - the password will be
given in class.
- Week 1:
- Lecture notes: units, metric
system, significant figures, dimensional analysis
Scientist article about attempts to define the kilogram standard,
and here is the result (video): the World's Roundest
Object (with a good presentation of the origin of the kilogram mass
- Bird poop and miles per gallon - Dimensional analysis and units cancellation humor.
- Field Studies of Pedestrian
Walking Speed and Start-Up Time - research paper on speeds of
elderly pedestrians crossing the street. Note the use of feet per second and meters per
second to quantify walking speed.
- Week 2:
- Lecture notes: vectors.
- Vector addition process - applet that animates tip-to-tail addition.
- Week 3:
- Lecture notes: representing motion
acceleration curves applet
- Modeling the energetics of 100-m running by using speed
curves of world champions, by Laurent M. Arsac and Elio Locatelli
J Appl Physiol 92:1781-1788, 2002.
- Wired Science: Bolt is freakly fast, but nowhere near human limits
- Deadly strike mechanism of a
mantis shrimp. Also see this TED
talk and (So-called)
Fastest animals on Earth. In fact they mean "fastest" in terms of
acceleration, not speed. Don't make this mistake!
- Another quadratic solver/plotter (opens in
a new window). Remember that acceleration appears in the quadratic equation of motion as 1/2 a t2.
- 1-D constant acceleration applet. For this to work, keep initial velocities in the range [-10,+10]
m/s and accelerations in the range [-2, +2] m/s2.
- Diving into
30cm water from 10 meters - from "Stan Lee's Superhuman" series.
Calculate the time of flight and impact speed (neglecting air drag).
Then calculate the acceleration (upwards) after he hits the water.
