Transcript of Velocity and Time-Distance Graphing

Graphing Motion and Velocity
Today, you will learn how to graph the speed and velocity of an object.
First, you should know the terms involved with this topic
Example
Mrs.Williames and Mr.Wisnewski had a race. Mrs.Williames was in the lead at a speed of 400 meters per minute. Mr.Wisniewski was running 300 meters per minute for four minutes but then stopped to help Nicole and Michelle with double method. When he continued running he ran at a constant speed of 400 meters per minute.

P4
Slope- the steepness of a line on a graph
X axis- the horizontal axis on a graph
Y axis- the vertical axis on a graph
Speed- Distance an object travels per unit of time
Velocity- the speed of an object and the direction of its motion
Helpful Equations
Slope=Rise or Change of Y
Run
Change of X
Speed and velocity=Distance
Time
Here is an example of how to determine slope
If it rises three and runs two, the slope is 3/2 or 1 1/2
Time= Distance
speed
Distance= Speed x Time
How do you organize your data?
Answer: A Distance-Time Graph!
The x axis will always be labeled time.
The Y axis will always be labeled distance.
Each axis must have equal intervals, all of the numbers you are working with, along with a title (and key if needed).
Positive Slope-
Distance traveled increases as time does
Stationary or constant speed (The object doesn't cover any distance during the time and has a slope of zero)

The winning table gets candy!!!
On a distance-time graph, does distance or time go on the x axis?
?
?
Answer:Time goes on the X axis
What's the difference between speed and velocity?
Velocity
Speed
?
?
Answer: Velocity includes both the speed and direction in which an object is traveling.
What's the equation for speed?
Speed= Distance
Time
What is slope?
Slope is the steepness of a line on a graph.
Is the Y axis vertical or horizontal?
?
?
The Y axis is the vertical axis.

Barbara's 2 Mile Run
The time started at 1 minute instead of 0 minutes.
If Sarah has driven 30 miles in ten minutes, what is her speed?
Her speed is 3 miles per minute or 180 miles per hour
THE END!!!!!

Questions?
?
?
Negative slope-Distance from beginning point decreases as time increases.
Rules
The first person to raise their hand gets to answer.
They must begin answering within three seconds.
