Graphs

Description
Analysis. ->graphical->verbal->physical
State any observations ala " Richies potty chart"
Conclusions about the lab
Relationships!
It's actually due on Friday because a lot of people are going on that Spanish trip. That gives you times to really observe the graphs and come to conclusions.
Molly's right. It would be what the slope stands for, and if anyone's unsure how to find that out, just start off simple with slope = change in y / change in x. Replace x and y with what the axes really are, and it would be velocity or acceleration.
Well, it does depend, because there are verbal, graphical, and physical. A graphical or verbal analysis could include a negative increase in velocity, but you would have to include more. But yes, make observations on the data.
You should be recording all your observations and data analysis in your notebook or with the graphs on the lab sheet. This is to discuss observations and ask questions.
Bree- it means relationships between all the position graphs, all the the velocity graphs, or between a velocity and a position graph. similarities and differences
ok so idk if we post here but im going to do it anyways.... so during the lab i noticed that within every V vs T graph every single slope was the same. They were also all parallel. Also, if you just look at the diagonals on a V vs T graph you will be able to understand the negative, constant concept of increasing in a negative direction if you think about each individual line as its own lab. For example if you throw a ball upwards or drop a ball, the velocity graphs would look exactly the same- downward. Every V vs T appeared to be going down for both directions the car was going- up or down the ramp. Remember since we called down negative, every time you do this lab the V vs T graphs will basically look the same EXCEPT if you started the car at the bottom and let it go upwards by magnet, or applying a force to push it. Then the graph would go up like / instead of down like \. Also every time the P vs T parabolas were at it's relative max's and min's, the V vs T graphs were at zero. And when the slope of a P vs T graph is zero, the velocity is also zero. The P vs T graphs also reminded me of the 12 graphs of physics with the yo-yo and basketball. It's the same concept.Some people might wonder why if they started their car in front of or behind zero the graphs look relatively the same. Well, the car is doing the exact same thing, just in a smaller range but it doesn't matter because things that look the same, are the same. so the main question: QUE ES VELOCIDAD? Well, Velocity means speed with direction, but acceleration is measured by how much force of gravity is being applied to the car. So technically even though we are saying that the velocity is negative and constant, the acceleration (or deceleration) of the car is negative and constant. ~ Gianna B.
Yeah I noticed the same thing when we were going over the graphs. You worded it very well even if it was long. But my question is that if the velocity and the acceleration are both negative and constant, would the acceleration be the same as velocity if the velocity changed.. Like would they always be the same? Ex: Velocity= Positive and constant would the acceleration be positive and constant too?
Yeah, the acceleration would be positive and constant too. The only difference would be when you graphed them, because the velocity would be linear and the acceleration would be linear with a slope of 0.
I understand how the velocity's slope is negative and constant when it's on the ramp. But when it hits the bumper on one end, and the graph goes almost vertically, the slope can't be negative, can it? -Kevin Meglathery
That'e when the slope changes, so you're right when you say the slope can't be negative there. I think it changes from negative to positive every time it hits the bumper and goes back down the ramp, but at a smaller velocity than the previous times it went down.
To clarify: The SLOPE of part of the velocity vs. time graph is negative and constant and is its ACCELERATION. But a negative and constant VELOCITY would be a horizontal straight line below 0 and would have no acceleration. (Gianna B. you were just missing a couple words at the end)

Considering this isnt due until thursday, i can come in an ask questions in class about it tomorrow right
ReplyDeleteIt's actually due on Friday because a lot of people are going on that Spanish trip. That gives you times to really observe the graphs and come to conclusions.
DeleteWhat is everyone doing for pictures?
ReplyDeleteSimple right triangle ramp with box car on it.
DeleteUsing arrows.
What does it mean to interpret the slope?
ReplyDeleteTo see if it is velocity or acceleration I think
DeleteMolly's right. It would be what the slope stands for, and if anyone's unsure how to find that out, just start off simple with slope = change in y / change in x. Replace x and y with what the axes really are, and it would be velocity or acceleration.
Deletefor analysis... is it like for example the velocity is increasing negatively? things like that ?
ReplyDeleteWell, it does depend, because there are verbal, graphical, and physical. A graphical or verbal analysis could include a negative increase in velocity, but you would have to include more. But yes, make observations on the data.
Deletewhat about relationships? like relationships between what ?
ReplyDeletewe are posting our answers right here right?

So are we recording all of this on the sheet with the graphs, or in our notebooks?
ReplyDeleteI guess that's completely up to you. Whichever way works best for you and helps you understand it the most.
