Period 7 discussion
Describe each motion. Think about the starting conditions and ending conditions for each motion
i.e. position & Velocity---> mathematically
Graph the following
On the first day of physics....
Graph an elf sitting in a tree
2nd Day of Physics
Graph an Elf ice skating
3rd Day of Physics
An elf skating backwards (Forward is the positive Direction)
4th Day of physics...
An elf on the roof dropping an iPad from rest (down is negative & ground is zero)
5th day of physics...
A physics elf driving in remote control car moving forward at constant speed and suddenly throwing it in then throwing it backward and reaching constant speed.
6th Day of Physics
A plate of stale physics cookies that have been thrown in the air and the crash on the ground... Be mindful of your starting and ending positions...
7th Day of Physics
An elf on a pogo stick....
8th Day of Physics...
An elf playing with a yo-yo, graph the yo-yo not the elf!,,
9th day of Physics...
A physics elf skydiving from a hot air balloon then pulling his parachute and safely returning to the ground.
10th day of physics...
A day off!
11th Day of physics...
A basketball released from the bottom of mainlands pool.
Be sure to label the top and bottom of the pool.
So basically, we just have to draw the graph related to each situation and analyze it by describing the velocity, position and acceleration?
ReplyDeleteyeah we just draw out the graphs and number them, and then we describe the slope like we did in class: positive, negative, zero, constant, ect.
DeleteAlright, thanks Kara!
Deletejust the 3 graphs?
ReplyDeleteThere's going to be a total of 12 graphs that we have to create. Follow the link he posted up there to print two sheets of the graph paper, and that's what you would use for each scenario.
DeleteHow will there be 12 graphs? I'm just a little confused.
Delete~John DiNofrio
It might just be my computer but I can only find 6 graphs. Will more be posted each day?
ReplyDeleteI think he might post more. Thanks for the help.
Delete~John DiNofrio
Every day he posts a new scenario for the graph, so by the last day of break, it will be 12 total graphs.
DeleteYup, there will be more graphs coming every day!
DeleteIf a graph looks like a square root function graph but goes in the negative direction can it be labeled as a negative squirtic graph? It still starts at 0 but goes into the 4th quadrant
ReplyDeleteIt would be negative squirtic because it is going to the 4th quadrant and since the 4th quadrant is below the x-axis, it is negative.
DeleteDoes the elf skate at a constant speed?
ReplyDeleteMost likely since it is skating on ice which is frictionless
DeleteIs the elf on the pogo stick doing anything other than bouncing straight up and down? And is the one with the yo-yo doing any special tricks, or just up and down as well?
Delete-Kevin Meglathery
DeleteI think he wants us to make the assumption on those two that the elf is going up and down at a constant rate and dropping the yo-yo up and down at a constant rate.
Deletewould the yoyo graph resemble the first graph we had to produce on the motion sensor? just constant curves up and down?
Delete@Aaron Myers Every substance in the world has friction, including ice. Ice just has very very little friction.
DeleteI graphed mine at a constant speed, Robyn.
DeleteCan someone clarify the 5th day of Physics, please?
ReplyDeleteSure... Think about what the car starts... How it will change?
ReplyDeleteWill it stop? After it stops then what will it do?
an elf sittng on a tree? i dont really know how i would graph this
ReplyDeleteThink about it: is the elf's position changing as time time passes if it's JUST sitting in the tree.
Deletethink about the end behavior of the elf if he's still just sitting there
DeleteThanks for the help.
DeleteAlso, does there have to be specific points?
ReplyDeleteI don't think so. Just sketch a graph that would best resemble each day.
DeleteThanks
DeleteSo for number 2, is the elf skating in a straight line?
ReplyDeleteWe're assuming it's skating at a constant rate from the starting point, so yeah, it's basically skating in a straight line from the starting point.
Deleteok thanks
DeleteI saw a few different posts for this event. The elf would be skating in a straight line, but it could change speed. I had the elf start with a position of zero and increase its slop (accelerate) as time went on. Just wanted to see what you guys thought of that.
Delete~John DiNofrio
so for number 4 we`re graphing the motion of the ipad right? not the elf?
ReplyDeletethere is no motion of the elf dropping the ipad, besides letting go. The ipad is the main part of the diagram. It sounds more realistic that something is dropping it.
DeleteYes, we are only graphing the motion of the ipad, not the elf.
DeleteFor the 6th day of Phsyics, are we just drawing one line? Or do you want us to draw a bunch of lines showing ALL of the cookies?
ReplyDelete-Jake Naumann
I never thought of it that way. I would assume that it would be just one line since he didn't specify how many cookies were on the plate, and they would end up being similar lines anyway.
DeleteThanks Nazia.. Just wanted to get someone's opinion before I started to graph mine..
Delete-Jake Naumann
I'm not really understanding the 9th graph can someone help me..is he going in a negative direction from 0? or.....is the hot air balloon at some higher point? if so what point
ReplyDeleteVince P.
It would be going in the negative direction, just not starting from zero. You would have to assume that zero would be the ground. When the elf jumps from the hot air balloon, it's at a higher point and I just chose a reasonable position for it.
DeleteNobody make the same mistake as me, we are not drawing the scenario on the graph paper (I drew an elf ice skating) we are graphing the motion of the scenario.
DeleteDay 5 really makes no sense to me at all, did anybody interpret it differently than me?
ReplyDeleteThat one confused me too. At first I thought there was a typo, but I think what it is saying is that the elf is steadily going forward, and then all of a sudden goes steadily backwards. I got a rounded corner shape on my graph. I'm not 100% sure that my interpretation is right, but I hope this helps.
Delete~John DiNofrio
It probably makes sense if you understand car terms, which I certainly don't.
Delete-Keivn Meglathery
i though when it said that he suddenly "threw it in" it meant that he changed direction very rapidly causing it to have all of a sudden a sharp corner. Then it evened out again
DeleteHe also said that it threw it backward, and that's what ended up confusing me. I thought that maybe it was a typo and he meant to say "he threw it in reverse" which caused the car to suddenly slow to a stop and go backwards in the negative direction at a constant speed.
DeleteI think it just mean the car is in drive(so it is moving forward) then the elf puts the car in reverse and drives backwards, where he was just driving forward if that makes sense.
Delete-Molly Lawlor
So Molly, when you graphed that did you just have two linear lines?
DeleteThat's the same way I interpreted it too.
ReplyDeletewhat are the x and y axis labels? Are they (position and time) or (position and something else)?
ReplyDeleteI made the x axis time for all of them, and the y axis was position, but sometimes I changed the Y axis from being horizontal position to vertical position (height).
Deletethank you harrison! now i can label them accordingly.
DeleteAlso would the elf ice skating be at zero? because he's on the ground?
ReplyDeleteYou would be graphing the motion of the elf in this case, not the actual elf. The elf is moving at a constant rate on ice which has no friction, so your graph should be linear.
DeleteNazia, when you ice skate you aren't going the same speed the whole time. First you start off slower until you get to a constant speed.. So wouldn't the graph be curved?
Delete-Jake Naumann
I made the assumption that the elf was going at a constant rate, but I see your point that it gradually goes faster. Like Mr. Crane says, there's no right answers in science. We have to prove it with our observations, so both of us could be right.
DeleteYou are completely right. Just like the cookie one, it's up to how you see it. I guess a lot of these graphs will vary depending on how you look at them.
Delete-Jake Naumann
thanks Nazia. I figured it out after i read reread it a few times. It makes sense that its linear because the slope is constant.
DeleteHow would i describe a graph like day 9? because its not really linear and has 3 different slopes at least mine does anyway? Would i just write m= not constant, +/- ?
ReplyDeleteAlso do we need an equation like we did in class?
I did it like we did in class that one day. Split up the lines like A to B, B to C, ect, so it's easier to look at
Deleteokay thanks! thats what i ended up doing, but i didnt know if it was right or not.
DeleteMy computer isn't letting me print the Kongi Paper. Is it okay if I graph it in my notebook?
ReplyDelete-Derek Kneisel
Never mind, I have it working. -Derek
DeleteWhat did u guys say about 7 and 8? did you describe the slope?
ReplyDeleteI didn't identify the slope for those because it was constantly changing.
Deleteok yea thanks
DeleteI didn't say the slope for 7 and 8 I don't believe. I don't really know what to write. Does anybody know when the 12 th graph will be posted??
ReplyDeleteThat was my comment grace - Ashley lawler
ReplyDeleteWhen will the 12th day be posted!??? It's the 12th day!
ReplyDelete:o
~Gianna B.
I was wondering that to Gianna. -Ashley lawler
ReplyDeleteI just wrote nothing was posted, but going to look later just in case something is posted.
ReplyDelete~Molly Lawlor
Someone help me with the yo-yo one... what is it doing ? simply going up and down??
ReplyDelete-Vince P.
Yeah, it's just going up and down.
DeleteI graphed the yo-yo going up and down, but not touching the ground
Delete~Molly Lawlor
You have to make a generalization, so basing your graph off of the common use of a yo-yo would be a good thing, so going simply up and down would most likely be fine, that is what I did.
Delete~Thomas Black
Molly, that's how my graph turned out and Thomas, that's what I did too.
Deletethanks guys..
Delete-Vince
Where is the 12th day?
ReplyDelete-Thomas Black
Yeh that's what i did for mine-Vince, but be careful of the starting position.
ReplyDelete~Gianna B.
Yea Vince that is what it is doing. -Ashley lawler
ReplyDeleteI guess we have no 12th day?
ReplyDelete-Jake Naumann
He's probably going to put it up a little later or in the morning. If i were you i'd just check again in the morning or before youre about to go to bed.
DeleteWell, it's 7:10 in the morning and he still hasn't posted a day twelve. I'm sure he'll realize that we all were checking constantly, so I don't think there is anything to worry about.
DeleteKevin Meglathery
No 12th day still, so I am assuming we definitely don't have to do it.
Delete"throwing it in" means to change to a faster velocity and "throwing it backward" means to change to a velocity in the other direction right?
ReplyDeletethats what i assumed so i got a sharp incline then it went down sharply too.
DeleteI just interpreted it as the car was moving forward, and the elf then put the car in reverse suddenly and went backwards, or in reverse.
DeleteShould I have a scale in my graphs?
ReplyDeleteyes you should always have a scale so whoever else is looking at it knows what each mark on the graph goes by. It also helps with organization so each graph has constant intervals.
DeleteYes you should have a scale but make sure when you label zero it is in the right area.- Ashley lawler
ReplyDeleteAre the 12 graphs going to be on the midterm?
ReplyDelete-Matt Nazha
Probably something similar. I would make sure you know the different parent graphs and different situations that would create those graphs.
Deleteok thanks Nazia! how should i study though? should i just study all the major labs we did the whole year so far? - Matt Nazha
ReplyDeleteIt's more like understanding all the concepts in each lab. He also posted the Midterm Review for us, which would be really good to look through and review.
Deleteok thanks!- Matt Nazha
