Physics 9-15-10 Chapter 2 Test

Good luck studying for the chapter 2 test. You’re going to do great! I’ll be praying for you!! Help session tomorrow morning at 7:15. Any questions?

1. just to clarify…on the formula: Average Velocity= D(1) + D(2)…./ T(1)+T(2)….

D(1) and D(2) are the displacements correct?

[D(1)= Distance Final minus Distance Initial (of one)]
[D(2)= Distance Final minus Distance Initial (of two)]

??????????

• Nate – Yes, but it’s probably not going to be that complicated. Usually on these problems you begin from a position of 0, so your displacement is your distance. If it isn’t given you’ll have to find d by saying Vavg x time for that particular interval. We mainly had to really begin to distinguish between the two when we started vertical motion and throwing an object up into the air.

2. i just posted a long post and didnt go through….wow…anyways the jist of that long quote was: in the average velocity formula with D1 AND D2/ T1 and T1….is D1 and D2 displacement of Distance initial 1 Distance Final 1 and Distance initial 2 and Distance final 2

• Nate – It did go through – just got caught in the spam filter, but I set it free. I responded to you – go back and see if you can find it. Or never mind, here’s what I said:

3. Ms. Skinner, do we have to have a non-graphing calculator when using it in class, or just for tests?

4. Cara C., its only on tests.

5. so i actually didnt think the test was that bad today. ill just see what my grade says about that. lol

• JT – Physics – no SItN; but just in case any other students are listening – chemistry, yes!
