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.
If you wanted to "give someone a break" you would break them off a piece of this chocolate candy.

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 type of candy can have an explosive reaction when it comes in contact with Diet Coke.

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 candy bar was named after a famous baseball player.

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.)
This type of candy was the first to go into outer space. It was taken aboard the Space Shuttle Columbia in 1981.
