(Actually we should call it 'speed', since the graph conveys no information about the direction of the motion, only the speed. Similarly, the distance we'll find won't tell you how far from the starting point you wound up, only how much road or track you covered.)
On the graph, there is some straight or wavy line representing your speed at every instant.
-- Pick the starting time and ending time of the interval you're interested in. Draw vertical lines on the graph at the starting and ending times, long enough to cut the wavy line that represents the speed function.
-- From the value of the function at the start-time, (the point where the 'start' vertical line cuts the graph of the function), draw a horizontal line, all the way across, to the 'end' vertical line.
-- Now you must measure the area of the space bounded by the speed graph and the three straight lines you have drawn. This is easier if the graph was drawn on paper that is marked off in a grid of small squares.
There may be places where the function is below the horizontal line, as well as places where the function is above it. If so, list the area of the space where the function is below the horizontal line as a negative number.
-- When you're done, add up all the positive and negative pieces of area you have measured. The result is the total distance that the moving object traveled during the time between the 'start' and 'end' lines.

im gessing yes
ReplyDeleteYou can tell velocity with a time graph because velocity needs time to tell velocity.
ReplyDeleteYes because it is speed/distance=velocity
ReplyDeleteYou can tell velocity with a time graph because velocity needs time to tell velocity. I copied Collin.
ReplyDeleteyes because speed can be showed on a graph.
ReplyDeleteYes because velocity and time are need to tell eachother.
ReplyDeleteYes you could use a distance and time graph to show velocity. You could because velocity is distance and time.
ReplyDeleteYes because you use time to tell velocity.
ReplyDeleteYes you can tell velocity with a time graph.
ReplyDeleteyes you can use a distance time graph to show velocity because you need distance to equal velocity.
ReplyDeleteYes, because you need distance to equal velocity.
ReplyDeleteyes you can use a a distance time graph to show velocity because velocity is time and distance.
ReplyDeletespeed/direction the answer is no
ReplyDeleteNo because there is no direction.
ReplyDeleteyes, because you can use a time graph.
ReplyDelete**distance time graph
Deleteyes you use time to see velocity
ReplyDeleteno, no direction(:
ReplyDeleteI don't know what a distance time graph is so i'm going to guess and say no.
ReplyDeleteYes because velocity and time are need to tell each other.
ReplyDeleteyup
ReplyDeleteno because it's missing direction. You cannot get velocity without it because the only way to get velocity with speed and distance.
ReplyDeleteCould you use a distance time graph to show velocity? Why or why not?
ReplyDeleteNo. You could not use a distance time graph to show velocity because velocity is speed/direction.
No becuase you can not use distance time graph
DeleteNO because distance is not velocity, velocity is speed and direction.
ReplyDeleteNo you couldn't use a distance time graph to show velocity because velocity is speed/direction. :)
ReplyDeleteno i dont know
ReplyDeleteNo you can't use a distance time graph to velocity.
ReplyDeleteHannah
Velocity is speed and direction but you have to have distance to go
ReplyDelete(Actually we should call it 'speed', since the graph conveys no information about the direction of the motion, only the speed. Similarly, the distance we'll find won't tell you how far from the starting point you wound up, only how much road or track you covered.)
ReplyDeleteOn the graph, there is some straight or wavy line representing your speed at every instant.
-- Pick the starting time and ending time of the interval you're interested in. Draw vertical lines on the graph at the starting and ending times, long enough to cut the wavy line that represents the speed function.
-- From the value of the function at the start-time, (the point where the 'start' vertical line cuts the graph of the function), draw a horizontal line, all the way across, to the 'end' vertical line.
-- Now you must measure the area of the space bounded by the speed graph and the three straight lines you have drawn. This is easier if the graph was drawn on paper that is marked off in a grid of small squares.
There may be places where the function is below the horizontal line, as well as places where the function is above it. If so, list the area of the space where the function is below the horizontal line as a negative number.

LOOK WHAT I FOUND ON WIKI ANSWERS!
and you cant use it because velocity is speed not distance and its direction
ReplyDeleteno you cant use a graph
ReplyDeleteyes u can
ReplyDeleteyou cant use a graph
ReplyDeleteYou cant use a graph because direction would not be shown.
ReplyDeleteYes, you can.
ReplyDeleteno you cant use a time graph
ReplyDeleteYes because there are algorithms for figuring out speed with distance and time.
ReplyDeleteYes because if you know the distance and time (which the graph would show) you would be able to get the velocity.
ReplyDeleteNo because it needs the direction.
ReplyDeleteno because the direction.
ReplyDeleteLiz
No because velocity is speed and direction
ReplyDeleteNo, velocity has to show direction.
