- 3.5.4 Vapex = 0, but there is still acceleration at the apex is still there of course, because acceleration measures the CHANGE in velocity. So what is changing about the velocity at the apex? The DIRECTION of the velocity vector is changing.
-
- It’s REAL important that you understand this about the velocity and acceleration vectors.
-
- Remember, with the y vs. t graph of Free Falls the function is a section of a simple negative trio.

- Make sure you press the large cup button on the Kuerig
-
- 3.5.7 got us talking about the new “Green Equations” which are for working with air rocket launches.
-
- Determining the launch speed of the rocket using total time of flight (tau)
-
- Here is way to determine the launch velocity using ∆x and the angle to the apex.

- Pacman (friction and drag) eats mechanical energy and spits out heat.
-
- Heat is chaotic. Friction randomizes energy and, therefore, increases entropy.
-
- So the object loses kinetic energy as it moves through the air. We’ll talk about all of this next semester.
-
- No fighting the 2nd Law of Thermodynamics.
-
- PacMan ALWAYS eats. Pacman never spits those dots back out.
-
- THis is the result of PacMan (air drag)
-
- Blue Quad is an easy derivation. Now hanging in the room.
-
- THis is a good problem
-
- watch out for this one on the Test.
-
- 3.7.7d The speed will be 16 m/s at two different times on this problem. Once on the way up and once on the way down.
