THE CHALLENGE!

• You have three challenges in front of you.
• 1st. Challenge is Speed.
• Change the size of your gears and tires until
  you have the fastest car.
• 2nd. Challenge is traction and strength. Change
  your wheel type and or gears until you car can
  climb a 25 incline for 1 meter.
• 3rd. Challenge is work. Your car must pull wooden
  blocks equal to the weight of the car across a 1
  meter sandpaper track in the shortest time.

19
GOING FOR SPEED

• Keep a record of the changes you make to your
  wheels or gears. BE SURE TO GET AGO____
  NO GO________

20
GO FOR THE CLIMB UP THE 25O INCLINE

• Change your wheel type or gears until you can do
  the job.
• Keep good records of the changes you make.
• Be sure to get a
• GO_____ NO GO__________

21
HOW MUCH WORK CAN YOUR CAR DO?

• Its time to separate the real challengers for
  the play challengers.
• Configure your car to pull its own weight across
  sand paper.
• Calculate the work done.
• Work is equal to Force (F) Times (X) Distance
  traveled.
• WF X D

22
FORCE IS NOT MEASURED IN GRAMS

• FORCE IS MEASURED IN NEWTONS.

THE END

• For now that is.
