Physics 9-1-11 Acceleration, Pt. 2

Posted on by
12

PHYSICS: Hey guys, here’s the last of the acceleration formulas. Good job with the derivations! You’re doing really well with them – stay with it! Carefully examine what you know with the formulas you have that might fit. And if they don’t, examine what you do know that could lead you to what you need to know. You know? :)

Tonight’s problems might be a little challenging, but you can do it!! Do you need some extra practice rearranging the formulas, or just working the problems? Help session next Tuesday morning. Somebody better text me!

Physics 8-31-11 Acceleration

PHYSICS: Great intro to acceleration! How do you feel about the formulas you helped me to derive? Go ahead and start the homework, and we’ll finish the last formula tomorrow – yes, there’s just one more. I think you’ll come to find these are a ton better than some of the velocity problems you did. List what you are given and what you’re looking for – don’t forget things like “starts from rest” and “came to a stop.” Then, just find the formula that contains the variables you are looking for. Easy peazy! Okay, maybe not that easy! :)

Physics 8-26-11 Velocity Problems 2

PHYSICS – Velocity problems from Thursday – you’re doing a great job on these! Let me know how the take home lab is going for you. I think it will be a good break from your typical type of homework!

Good luck on those five problems. Try not to look at your notes, but if you do, work it again without your notes! And make sure to do more than just show the math – be sure that I can also follow your logic in the formulas. Ditto with units, etc. Don’t give up on the tortoise and the hare. A couple of hints: remember the distance the tortoise travels is the same as the distance the hare travels plus the extra 20 cm he was ahead. Also, the time the hare raced is equal to the time of the tortoise minus those two minutes he rested. Now go have fun! :)

Physics 9-7-10 Velocity & Acceleration Worksheet Problems

PHYSICS: Who knew – there really is such a thing as cockroach racing! In lots of places. Aaaahhh, I just might have nightmares now! By the way, can you see it? No, I mean can you see how much progress you’ve made on these acceleration problems? You are doing great – keep going, don’t give up!! Here’s an overview of numbers 3, 4 (the cockroach problem), and perhaps the formula for number 1(?) from the end of class on Monday. Are you ready for tomorrow’s lab – that is if it doesn’t rain! Oh, and put it on your calendars – help session this Friday, 7:15 A.M.

PHYSICS: Thank you for your work today – you did a great job! Do you feel a little bit better about the problems? Let me know WHEN you want us to have that help session. I think we need to practice re-arranging formulas – do you need help with something else? Did you get a Velocity-Acceleration Worsheet for tonight’s home? If not, click on Velocity-Acceleration Worsheet and magic will happen. Hope you have a great weekend!!

Physics 9-2-10 Acceleration Review (& the Deer Problem)

Posted on by

PHYSICS – Here’s the review we did on acceleration today – conceptual stuff at the first, and then problems. In this one, we went over HW: 12 – 15ish, then problems 20 – 25, and 41 – did we get to #42? This includes the deer and park ranger problem. Don’t freak out if you aren’t getting the exact answer – it could be a rounding issue. See you in the parking lot tomorrow – are you ready for a break?

PHYSICS – Velocity problems from Thursday – you’re doing a great job on these! Thanks, Taylor, for explaining #11 a different way. I think I like your way much better than mine – it seems simpler!

Good luck on your homework. Don’t look- you know what I mean! And make sure you’re not just showing the math, but that I can also follow your logic in the formulas. Ditto with units, etc. Don’t give up on the tortoise and the hare. A couple of hints: remember the distance the tortoise travels is the same as the distance the hare travels plus the extra 20 cm he was ahead.

PHYSICS: Hey guys, here’s the work we did on the homework from Tuesday night, problems 9 – 11, especially number 11. :) Now, don’t just copy your notes! You go back and work number 11. Did we work it right in class? Why didn’t we seem to get the right answer? What did we find and what were we trying to find? Come on, you can do it! Hey, how’s the velocity lab coming? A different kind of homework – do you like this better than written work from the book?
