Position vs time Assign 1 Sci 9

The a position vs time graph ______ is graphed on the X-axis.

• time

• position

• both time and position

• speed

On the Y-axis of a position vs time graph ________ is graphed.

• time

• position

• both time and position

• speed

Which graph matches this statement:

The object did not start at the origin and moved to the left the entire time.

• Graph a

• Graph b

• Graph c

At what time does this object begin to move left?

• 3 seconds

• 7 seconds

• 10 seconds

• never

Consider the position vs. time graph below for runners A and B.

Which runner is ahead at the beginning (zero seconds)?

• A

• B

• A and B are at the same position at zero seconds

At t= 5s, which runner is ahead?

• A

• B

• Runner A and B are at the same position at 5 s.

Which runner is travelling faster at t = 7s? (what part of the graph indicates "how fast")

• A

• B

• Both runners have the same speed.

Which runner has a greater change in position at the 10 s time?

• Runner A

• Runner B

• Both runners have the same change in position.

What is happening at the intersection of lines A and B (this is at the 5s mark)?

• The runners stop.

• The runners have the same speed.

• The cyclists are at the same position at the same time.

What was our first experiment with cars? (hint: look at page 6 in your packet!)

• Buggy Cars moving at constant speed

• Buggy Cars speeding up going down a ramp

• Buggy Cars climbing up the wall.
