okay this is the motion lamp and what I'm going to do is collect the data so I have it set up here I have the lab quest set up here with a motion detector on I'm attached over here to my iPad what were the information will come off as I collect data I have a cart that's attached to a string and then there is a weight that's going to go over a pulley that will pull the card and we want to look at the motion of his part so first thing we're going to do is try to pull look at graph of it moving and then we want to label something so I'm going to try to put you over here see if maybe you'll be able to see down the track the cart now so get this all set up okay so we're back in set up here so that's the run now we want to look at the data that we got so if we look at the iPad here's what's coming up we got a nice graph of motion this is position versus time and you can see that it's flat in the beginning that's normal because we're holding it's not moving and then I let go and then it's curves slightly that means it's accelerating that's when the wait was traveling towards the ground and then this is after the weight is hit the ground is moving at a constant speed and then if it sits there that's where it has hit the end stuff and it turns back and goes Direction so what we want to do is draw this so they should be drawn in step by step 10 here and then label those three points in case you wondering where those three points are I just said where they were so you can rewind the video and check that out so you might want to stop the video right here and pause it on this and give that a good good little sketch down at the bottom and then the next thing to do is go to the back here on the back we're supposed to be collecting data about the the slope okay High I've got some runs here I have over 10 runs when I was video bring the iPad it didn't turn out too well you couldn't really read the the data so I'm trying to do this again and try to get you the information so now we're on the back of the lab where in the data table where we have to collect 10 speed so we're going to collect the seeds I have run one so up there on the left side of the Promethean board you can see the runs I'm doing position for Run 1 this is what the graph would look like and I want to highlight an area where it was moving at a constant speed and then I want to do a linear feet to that area and I want to get to slow so you can see a couple boxes of here I'm going to try to see if hopefully this video if I zoom in now you might be able to read the slope here so this first love you can't read it it's .920 920 is what that still freeze FM from the formula y equals MX plus be so maybe if I can just I'm going to run through I'm here I'm going to highlight and then I'll turn off the data and hopefully you can read those if you're not able to listen to this if you are able to listen to it also read off what the reading was so that was the first one now will go to the second one so pull up another addiction graph here from another run looks very similar to the to the last one if you could see the whole thing so the zoom out here a little bit that's what it looks like same type of thing that we saw on the last one and I'm going to highlight an area are going constant speed and do a linear fit and on this one if you can read it it's .950 is the is the slope on that 1.950 so let's go to the next one accidentally hit the next one before I took the last one off so this happens it takes a little minute and I don't want that part to be done I need to highlight a better party still accelerating down in the area that was chosen so I'm going to delete that I want to do a new one so this 1.96 50.96 5 and that should be our third one let's go to war so just be patient with me is Google CEO and we don't want to highlight that area that's highlighted so I got to go and delete this one can if we can just get rid of that one here we're on our on our fourth run here so I'm going to try to pull that one up again there we go so now I'll highlight the right area a linear fit there and this one is .925 0.925 but let's go to our fifth one second a good place we could probably do that one point nine 02 2.902 is what the then we're going to go to work 6 to 1 now should be filling in number 6 on the data table so this one looks similar to the others I'll do a little highlight Mariah with moving with constant speed linear you're done so this one is .923 0.9 to 3 moving to the next one that should be our 7th I only get to the right area to highlight year this one is 0.92 60.92 6 is what it reads and then we'll get rid of that one that's we've been 702 number 8 there it is a little highlighting there linear fit El Camino slope is speed and this one says 0.94 to 0.942 so this should be our ninth one now point nine 460 .946 and then this can be the last run here I think I think we should make it so that there was 10 of them there we go .923 on this on it's already highlighted in a good area and one neat I want to see is this number the cor our number is 1.000 that means the points that I have highlighted exactly line up like a straight line they are a straight line so that's good information that is moving at a Speed 2 if we see the correlation of the points two are linear fifteen hundred percent is basically what that means average and then finish up the lab
