Let's just do zero to 10, the whole thing. It for simplicity's sake for the total time shown on the graph. You can find the displacementīetween any two times here, we're just gonna find So one piece of information you can get is the displacement of the turtle. That's what this graph is representing, and that's how you read it. And then all the way back to three meters, so this turtle rocketsįorward back to three meters. Then what does the turtle do? After that point, turtle rockets forward. So between two seconds and four seconds, this turtle rocketed back this way. Now what happens? Turtle at some later time, four seconds, is at negative five meters.

Turtle was probably trying to figure out how to turn on her jet pack. Line on a position graph represents no motion whatsoever. We come over to the left toįigure out where we're at. At two seconds we come up, hit the graph. We read our graph by going up, hit the graph, then we go left to figure Now what happens? So at t equals one second, same thing. So at t equals zero, the turtle is at three meters. And the value of this graph is representing the horizontal position, so the value of the graph is giving you the horizontal position. And at t equals zero the value of this graph is three. If this turtle didn't goįorward, down, and up, what did this turtle do? We'll start at t equals zero. So let's just read this graph and figure out what this So somewhere at like two and four seconds this turtle was at two meters. What that means is if you find the turtle at some point over here at x equals two, then the graph should represent that the turtle is at x equals two by showing the value is two.

In this case I wrote is as x, so this is gonna be And I'm doing that because look over here we're graphing. So I'm gonna label this x and it's gonna be measured in meters.

Graph actually says let me lay down a horizontal access here. So maybe the turtle went forwardĪnd then down and then up, but that's not right. The first mistake a lot of people make is they think that well maybe the shape of this graph is the same as the shape the And this graph represents the motion of this particular turtle. And I don't want a sternly worded letter. And instead of just saying object, let's make it specific. To write an equation or say a bunch of words.

Basically specify theĮntire motion of the object, and you didn't even have Why do so many people love these things? Because you could compactĪ ton of information about the motion of an object into the small little space right here.
