Making Paper Rockets and Make Up Day 1 of 2
The Einstein Board Today 11/25/2013
1. Short Video taken from Armageddon - The miners are on an asteroid where g is more like -0.8 m/s^2 so the horizontal velocity has a much longer time to travel since the vertical component down of the velocity is so little.
2. Last Friday - If you wish some extra credit for last Friday's jump through the burning ring of fire .... you must had in a hard copy with Purpose, Procedure, Data Table, the three Calculations ( v = s t, range formula, Max. Height), Conclusion, and Summary. Again this lab can replace a 10 pt. lab missed or up to 10 points on anything missing or poor score (anything but a test that is).
3. Last Wed. & Thurs. Proj. Motion Lab. The movie clip of a man shooting a basketball analyzed with four graphs in Excel due tomorrow. Drop it into the drop box ASAP. I showed the five students who had already dropped it in last week on the screen in our classroom.
4. Turn in the homework problems for this unit by the end of the day tomorrow.
5. When we get back from Thanksgiving Break it will Dec. 2nd and review of the Unit 4 test on projectile motion. The test will be Tuesday Dec. 3rd and Wed. is early release day and Thursday we'll start the last unit of this year Unit 5 on Circular Motion.
6. Making a paper rocket for tomorrow.

This Projectile Motion Unit 4 in a Nut Shell (before the nuts are used for Physmas Cookies)
Just TWO parts:
1. For Projectile Motion shot at a zero degree angle (Horizontally Shot out)
The horizontal velocity is Vx = Sx / time (so in the Bulls Eye Lab you measured the time it took the
marble to roll 1 meter across the table top)
Then the height of the horizontal shot will give you the time to fall (horizontally or vertically)
since Sy = 1/2 g t^2 then t = the square root of [(2 * Sy)/g]
Then the range (where the projectile will hit the ground from where it left the gun) is:
Sx = Vx * t
2. For a Projectile Motion shot at velocity V and angle theta
Note diagram on the Objective side of this homework sheet. The hand at the bottom has all six formulas you need to know how to use on the test Dec. 3rd, 2013.
3. Here is my Projectile Lab with graphs and the Big Picture behind each graph.
My Projectile Lab and here is the original lab handout procedure for the Projectile Lab
