4. UNDERSTANDING UPWARD FORCE - The ball has an initial velocity upwards imparted by your hand. This gives it a speed but the instant it leaves your hand only gravity is in effect and it pulls backwards on the ball eventually slowing it to zero. The only force acting on the ball once it has left your hand is gravity. ... and friction and resistance from the air molecules colliding with the movement of the ball unless you neglect that. If a ball is dropped, then only gravity is acting on it from the moment of release but it starts at speed zero. If a ball is pushed downward, it starts at a different velocity but after the moment of release, it is only acted on by gravity.

3. Hang Time Explanation. a) The d = 1/2 g t^2 is only good for calculating this if you assume a straight up and down jump and not a parabola. If you have a jump with horizontal motion, then you must use the triangles as we explained with the rockets today. b) Here is the proper way to think about this. D= 1/2gt^2 is only good for a one way trip. It does not factor in the change in direction. That is where we went wrong. So you calculate d = 1/2 g t^2 for one way and then do d = 1/2 g t^2 for the other direction and add them up. That gives you the distance for the whole trip. Why did I explain it incorrectly in class? Well, because I was taking the whole trip TIME and applying it as if the object had been falling and accelerating the whole time. That is not true. It decelerates on the way up and accelerates in free fall on the way down. Using it for the whole time assumes constant increase in speed through the entire trip. I WANT AN EMAIL IF YOU DO NOT GET THIS. Try really hard to read it slowly and understand.

**What we covered to****day:**

- Predicting landings with rocket launches prelab exercises - Students, WATCH OUT. The first arch - you must remember that gravity pulls BACKWARD on something going up. If it launches at 60m/s, gravity pulls backward by 5m in the first second (from d = 1/2 gt^2) and a total of 20m by the time 2 seconds pass and so forth for each second until the ball reaches the top of the arch. From then on it falls as if it had been dropped in free fall.
- Start writing up lab 4. Objective: To predict the landing spot of a physics rocket using trigonometry. Or.....how much does wind and air resistance impact the accuracy of predicting rocket launches. Do the background focusing on projectile motion. The rest can wait.

The video is a little strange, but if you go slowly, you can understand it. U is the coefficient of friction - that is just a guide as to how effective friction will be at keeping something on a road. Also Tan -1 is a symbol for arctangent.
