Spinning lead a cube on a desk top. As the angular velocity slows the lead cube travels in larger circles.
I believe I had shutter speeds of 1/160, 1/320, 1/800. Man 4 minutes goes fast. The traffic on the way back to St. Louis was not so fast. Got back home to Minnesota at 5:45. Just in time to go to work.
Clear skies! 4 minutes sped up to 30s. It was dark….note star to bottom right.
I have a canon 5D mark IV with a 100-400mm telephoto. I’m going to try to get some photos during totality on Monday. What should I use for aperture, shutter speed, and iso? I just want to be in the neighborhood of the right settings when my 4 minutes start.
The initial translational acceleration of the end of the rod is 3/2g so it leaves the outer ball behind. Since the 2nd ball is less than 2/3 the way out, it stays in contact with the rod.
Idea for AP Physics 1 review activity is for them to describe the difference between the pair of terms. Then the partner decides which concepts are being contrasted. I haven’t got to rotation or shm yet. Is there some I’m missing? Maybe negative acceleration vs. deceleration?
Today in physics…Mass vs sledding speed…1st a small scale model…then to the hill.
Rollerblade demo…Sideways motion doesn’t affect vertical.
I have students calculate the angle the dart makes with the wall on impact. Sometimes they want to use x and y displacement from the barrel instead of x and y velocity at impact. The string helps them see the dart doesn’t drop much until the end.
Red, blue, and green light sources at slightly different angles cast different shadows. If all 3 shadows overlap we see black, 2 shadows lining up gives a primary (the color not shadowed). Where there is a single color shadowed we get the secondary of the other 2.
I made this sheet for uniform acceleration practice. There is pattern to the answers, but it also forces them to use all the equations. I believe I will also have them right a question for each row to get them using the words.
While the students are taking their static electricity quiz, I’m busy building a static electricity elevator.
Only 10 minutes left of the Beaver Moon.
The balls have masses of 13g and 104g. They are dropped from 15cm (small) and 11cm (large). When stacked they rebound to 70cm (small) and 2cm (large). When not stacked they rebound to 12cm (sm) and 8cm (lg). The big ball loses more PE than the small gains from being launched.
The front tennis ball is falling, so the rebounding trampoline launches it back up.

Comet 12P/Pons-Brooks is near the western horizon soon after sunset. Its tail may be visible in a pair of binoculars. Astrophotographs will show a lot more detail like this image by @kilroi22 Use The Evening Sky Map (PDF) to find the comet's position. skymaps.com/tesm/
Tonight I managed to get 8 good 90s exposures of Comet 12P/Pons-Brooks and stacked them to eliminate some annoying satellite trails. You can see why early cultures called comets "hairy stars".

@DarekDewey ISO 100-200, maybe stop down a click depending on how good the optics are. If you can put it on a tripod, go for the 400 mm zoom. Use the bracket setting on the camera to get a range from about 1/1000 to 1/100. Get some longer ones, 1-2 s, to get earthshine. Clear skies!
@DarekDewey I did something similar putting nickels on a meter stick. The ones less then 2/3 of the way out stay on until they slide further out.

@DarekDewey Great idea! force of friction v coefficient of friction Depending on how you teach weight: 9.8 m/s/s vs 9.8 N/kg x v. y for projectiles I'm doing SHM now so these come to mind Spring force vs spring constant U_e vs U_g Force by a spring vs force on a spring Frequency v period
