THIS WEEKS SLIDE SHOW OF LAST WEEK:
( I will add captions before Monday morning. )
-
- Engineering — Dutch style
-
- The official Kilogram
-
- Kept under three vacuum chambers.
-
- PhyFl16P1SS21–A cesium clock is one type of atomic clock which is a primary frequency standard in which electronic transitions between the two hyperfine ground states of cesium-133 atoms are used to control the output frequency. The first caesium clock was built by in 1955.
-
- DImensions are different than units.
-
- Remember that a galactic year is the time it takes the sun to complete one revolution of the Super Massive Black hole in the center of the Milky Way galaxy.
-
- The intial and final position relative to the origin dictate whether the displacement will be positive or negative.
-
- 1.7
-
- Distance is total path length. Displacement only goes from the very beginning to the very end.
-
- Bike tires will collide in 1 hour since they are both moving at 10km/hr. Therefore the Fly will fly for one hour at 30 km per hour . So the fly will fly 30km.
-
- We introduced a little circular motion.
-
- So one radian would be when the arclength equals the radius.
-
- . . .
-
- This is why there are 2π radians in a circle.
-
- For practically every equation there is in the linear world, there is a corresponding equation in circular world.
-
- lower case omega represents angular velocity.
-
- all the kinematics we have studied so far.
-
- V = (omega) r is the bridge between circular world and linear world.
-
- Our first derivation!
-
- . . .
-
- Why radians have no units.
-
- 1.7.10
-
- 1.7.11
-
- Engineering
-
- . . .
-
- Baseball analogy
-
- . . .
-
- Our first duet! Slope graphs are also called derivative graphs.
-
- Slope graph
-
- piecewise function’s slope graph.
-
- . . .
-
- The Trippin run.
-
- from 1.8
-
- Distance vs. displacement
-
- 5 velocities (slopes of hypotenuses.
-
- The slope graph of this piecewise function is a step graph.
-
- Notice the open circles at the end of each segment.
-
- Average velocity is the slope of the line from the beginning to the end.
-
- 3D vector
-
- 3D vector
-
- good video on radians
-
- Space hotel
-
- why 360 degrees in a circle.
-
- Musk on Colbert.
-
- How hyperloop works
-
- Hyperloop map
-
- THis one was interesting.
