# Physics 9-29-11 Relative Motion

PHYSICS – We finally made it to the end of chapter 3! Here’s the lecture from Thursday on relative motion. (And I think there is an angular projectile motion problem at the end.) You know, we’ve done most of this already. The only new part is the motion of objects in the same direction and opposite directions, relative to each other. Don’t forget, you’ll use what you learned about vector addition to work those “boat goes across a river” and “plane experiences a head wind” types of problems.

I’m looking forward to hearing how the problem review in class on Friday goes. I think it will be great hearing from each other how you work the problems. And holler here via a comment if you have a question or need help. Did we decide on a help session either Monday or Wednesday morning? Somebody let me know. Good luck studying for the test. I’ll be praying for you!

So, i tried to understand why the velocity of light was not relative but constant but i couldn’t. It was fun though.

Thanks for letting us work on our problems again in class today.

3. Megan G P5 says:

Ms. Skinner…this is urgent! Is our Alternative Assignment (or Grice Vector Problem) due tomorrow, October 3rd? If so…can I just use a poster, or do I need a PowerPoint too? Just in case I don’t see your answer, feel free to shoot an email or text to my mother! Help!

Hey Ms. Skinner, when’s our help session this week?

5. Jakin D P5 says:

Could we possibly have an after school or lunch help session before the test?

Be strong and courageous. Do not be afraid or terrified because of them (Vector Problems), for the LORD your God goes with you; he will never leave you nor forsake you.”

To All – Amen, amen, and AMEN!! Thanks for the word of encouragement, Sebastian!!

I agree with Jakin. An after school help session would be the only time I can make it.
