3. Warm Up 3/10/15 Usain Bolt vs. Cheetah
Draw a motion map to represent the motion of both Usain bolt and the cheetah between 0 meters and 100 meters.
Usain Bolt’s time was 9.58 s at 100 m.
Cheetah’s time was 5.9 s at 100 m.
Hint: Remember the Jogger vs. Sprinter motion map.
T = 0s
T = 0s

6. A motion map represents position and direction at even time intervals.
HW 1-3 Motion Maps
A motion map represents position and direction at even time intervals.

7. How many jumps does it take?
Ladder Method 1 2 3
KILO 1000 Units
HECTO 100 Units
DEKA 10 Units
DECI 0.1 Unit
Meters Liters Grams
CENTI 0.01 Unit
MILLI Unit
How do you use the “ladder” method?
1st – Determine your starting point.
2nd – Count the “jumps” to your ending point.
3rd – Move the decimal the same number of jumps in the same direction.
4 km = _________ m
Starting Point
Ending Point
