If you did the self check and still have questions. You can discuss them here. If you understand the self check quiz you can help out your classmates by answering there questions.
The only question that has been asked is if there is going to be a quiz... If that is the only question, then the answer is yes. The self check quiz has help info, and an copious amounts of tutorials and information on the site. I will not be available for extra help tomorrow or the day of any other quiz or test. If you have waited until the day before a test to figure out that you have questions, its too late for me to help you.
#4 (It is not asking you about the slope) Ok with #4 the question asks if all the graphs were v vs. t graphs which ones would represent a positive v. It is not asking or referring to the slope of the graphs because that would be the acceleration. They are asking about the velocity
It simply is asking which graphs represent + velocity, or mathematically speaking which graphs have positive values (quadrant1)so that would be 2 Graphs (D & F).
Thank you for responding. I think I understand. The phrase "traveling in a positive direction" confused me because I thought it meant which quadrant the graph would be if extended.
Cool #9 + acceleration is defined as a velocity that is increasing,positively This can be done a couple ways 1) Start from a 0--->+ velocity 2) Start with a +--->+++++ velocity 3) Start wit a (-)--->0 starting with a negative velocity and going to 0 is the tricky one. But think of the definition of (change) Change=final-Initial ,like y2-y1 so in graph H the V starts out (-)--->0 see 3) look at graph I the starting slope(v)is 0 V 0--->+ also a + change in V therefore a + acceleration. The above are the explicit reasons why they are what they are. The notes below the question state a simpler way to determine this. While this explanation given works it does not explain the relationship between the variables.
I do not understand why in question 4 one of the answers is F. The slope looks like it's negative.

Could you also explain #9?

On the quest we're just graphing d/t, v/t, and a/t for a situation similar to one of the walks the walks questions, right?
ReplyDeleteJust like in class. Just like the HW. The self check quiz is to help you understand what's going on and make it easier to do the basic stuff.
ReplyDeleteOK no more physics>>> The Bourne Identity is on...
ReplyDeleteThe self check quiz was harder than class (i got 2 right the first time), but redoing it over and over has been very helpful.
ReplyDeleteThank you for your help!
Matt Damon > anything
ReplyDeletethe notes on a the self test are good. i would copy them down.....at 10 pm
