Check each other.
Should show a straight line across.
Draw an L-shaped axis.
This is what a velocity vs time graph looks like for an object that is stopped.
Check each other.
Should show a straight line across at zero.
This is the date when we celebrate Veterans Day in the U.S.
What is November 11?
A bus is traveling at 35 mi/hr and slows to 15 mi/hr in 5 seconds. This is its acceleration.
What is . . .

(Must have negative sign)
Use the position vs. time graph on the handout to determine the velocity of the segment B-C.
What is . . .
1 m/s?
Draw an L-shaped axis.
This is what a position vs. time graph would look like for an object going at a fast constant speed forward.
Check each other.
Should show a steep, straight line going upward.
Draw an L-shaped axis.
This is what a velocity vs. time graph would look like for an object that is moving at a slow constant speed forward.
Check each other.
Should show a straight line across, relatively low on the y-axis.
This war ended on the date in which we now celebrate Veterans Day.
What is World War I?
Superman changes his speed from 5 mi/hr to 50 mi/hr in 9 seconds. This is his acceleration.
What is . . .
5 mi/hr/s?
Use the velocity vs. time graph on the handout to determine the acceleration of the object in segment D-E.
What is 3 m/s/s?
Draw an L-shaped axis.
This is what a position vs. time graph should look like for an object moving at a constant speed backward.
Check each other.
Should show a downward straight line.
Draw an L-shaped axis.
This is what a velocity vs. time graph would look like for an object that is speeding up moving forward..
Check each other.
Should show a straight line going upward.
This is the war in which the highest number of currently living American veterans served in.
What is the Vietnam War?
A basketball is dropped from rest off of a building. It falls for 2 seconds and reaches a speed of 19.6 m/s the instant before it hits the ground. This is its acceleration.
What is . . .
9.8 m/s/s?
Use the velocity vs. time graph on the handout to determine the acceleration of the object in segment E-F.
What is 0 m/s/s?
Draw an L-shaped axis.
This is what a position vs. time graph should look like for an object speeding up as it moves forward.
Check each other.
The line should curve as it moves upward (similar to a J)
Draw an L-shaped axis.
This is what a velocity time graph would look like for an object that is slowing down while moving forward.
Check each other.
Should show a downward straight line.
This is the number of branches there currently are in the U.S. military.
What is 6?

If Mario accelerates at a rate of 1.5 m/s/s, this is how much TIME it will take him to get from a speed of 15m/s to a speed of 30 m/s.
What is . . .
10 seconds?
Use the velocity vs. time graph on the handout to determine the acceleration of the object in segment F-G.
What is - 1.5 m/s/s?
(Must have negative sign)
Draw a sideways T-shaped axis.
Draw a position vs. time graph for an object starting at the starting line moving backward while speeding up.
Check each other.
The line should go below the zero x-axis. It should curve downward moving a little at the start and then more as it goes down (like the second half of a rainbow).
Draw a sideways T-shaped axis.
This is what a velocity vs. time graph would look like for an object that is moving backward and speeding up.
Check each other.
Should show a downward diagonal line that is below the zero line of the x-axis. (Negative velocity for moving backward.)
The motto of the U.S. Marine Corps is "Semper fidelis". This is what that motto translates to in English.
What is "always faithful" or "always loyal."
