NEW SCREEN SHOTS WILL BE ADDED LATER SUNDAY.
-
- Stacking blocks gives them more mass. They have gravitational potential energy which equals mass from the Einstein’s equation E = mc^2
-
- For the same reason this arrangement of blocks has less mass (because less energy).
-
- Since the higher energy electrons are the furthest from the nucleus, they are the more massive electrons.
-
- . . .
-
- Here is the way we should write Einstein’s equation in here since this is more useful. The object doesn’t have to be static. With this equation the object can move.
-
- Back to Conservation of Energy
-
- One like this will definitely be on the test. It is the classic Con of Mom problem since it has two con of mom equations in one problem. First you have recoil with initial velocity, then you have an inelastic collision.

- SemiFormal!
-
- Great example of a 2D mostly elastic collision. The initial momentum of the cue ball in the “x” direction turns into a bunch of mometum vectors in the x and y axis. The weird cool thing is that all those post collision momentums have to add up to the initial momentum of the cue ball BEFORE the collision.
-
- The momentum before the collision will ALWAYS equal the momentum after the collision, no matter what happens in the collision. Sometimes you have to get down to the atomic level, but it ALWAYS works. It’s a law of nature my friend. : )
-
- Even in a fireworks explosion. If you add up all the momentums of the brightly glowing particles AFTER the explosion, they will have the combined overall momentum of the initial shell that was shot into the area. In fact, the path of the center of mass of the thousand after explosion particles will add to the intitial path of the shell to complete the parabola. Physics rocks!
-
- A simplified firework.
-
- Gotta love Craig’s List.
-
- Sometimes head-to-tail is the best way to deal with 2D collisions.
-
- Dane came! He showed the lunch crowd how to use a Galilean Compass. It was awesome.
-
- Hey, wasn’t that the same dirt that was in the NW corner of the construction zone last week? I think it took them less time to build the pyramids.
-
- Dr. Strauss!!!! will be here next week.
-
- Here is where he works in Europe.
