Soon, you will be starting a unit on distance, time, motion and how
motion is graphed. We'll start this unit with a few questions to see
what you may already know about them.
Please think about the
questions on the following pages and give your best answer.

A Race from North and South
Aaron and Zoe run a 50 meter race. The finish line is at 50 meters
as shown in the graph below. They do not start at the same position.
Aaron starts 50 meters North of the finish line and Zoe starts 50
meters South of the finish line. The graph below shows the first 30
meters of both Aaron's and Zoe's runs.
In running the first ten meters, how many seconds does Aaron take?1 second2 seconds3 seconds6 seconds15 secondsDuring the first ten seconds, how many meters did Zoe run?10 meters20 meters30 meters70 meters80 metersWho do you predict to win the race?AaronZoePlease explain your answer for the previous question.
The Building Elevator
The building in the picture has 10 floors. Three of the floors
are below ground level and seven of the floors are above
ground level.
Jim parks his car in the Level -2 garage. He
takes the elevator to Level 4.
How far did the elevator travel?2 floors6 floors7 floors8 floorsPlease explain how you got your answer.
Acorn and Berry
The diagram below represents a piece of train track along which two
towns named Acorn and Berry are located. The track happens to be
marked with mile markers as indicated.
The
red line on the graph below represents a trip of a train on the
track that connects Acorn and Berry as it moves in time.
How far did the train travel?18 miles25 miles6 miles4 milesWhen was the train stopped?It never stopped.It stopped at 25 minutes.It stopped from 0 to 6 minutes and 18 to 25 minutes.It stopped at 2 minutes and at 6 minutes.How long was the train actually moving?6 minutes12 minutes18 minutes25 minutes
Graphs Tell a Story
Graphs of motion tell stories of trips. The graph below represents
another trip on the track that connects Acorn and Berry. On this
graph, each part of the trip is labeled with a letter.
Which statement below best describes the story of the train's trip?The train went down into a valley and back up on the other side.The train went from Berry down into the valley, stopped briefly at Acorn, and returned to Berry.The train went from Berry to Acorn, stopped briefly at Acorn, and returned to Berry.The train went from Berry to Acorn, stopped briefly at Acorn and then travelled to a new destination.On which part of the trip was the train going the fastest?ABCDE
Sketch the Graph
Sketch a graph that tells the story below. Click on the pencil tool
to the right of the graph and use your mouse or stylus to draw the
graph. You can change your line by redrawing it, or clear it and
start over if you like. Remember, this graph is a sketch; it does
not need to be perfect.
The
train is stopped in Acorn for two minutes, but then leaves for Berry.
Three
minutes into the trip the engineer sees a cow on the tracks and
stops the train.
After two minutes, the cow moves on and the engineer resumes the trip.
When the train reaches Berry it stops for three minutes, and then returns to Acorn.
Speed
The graph below shows the movement of an object at several points in
time.
What is the average speed of the object?0.5 meters / minute2 meters / minute25 meters / minute50 meters / minute
