JOULE MOBILE
GOAL: Challenge students to design and construct a wheeled vehicle which will transport a 1 kg mass
using the energy released as this mass falls.
*No other energy power can propel the mobile.
*To be constructed and made outside of class.
*The mobile dimensions cannot be over 50cm wide, 70cm long ,90cm tall.
*Can work alone or with 1 partner.
*Need to see picture of work in progress (due date) =___________________(5pts)
*RACE DAY 1 (due date) =______________________(20pts)
*RACE DAY 2 (due date) = ______________________(40pts)
*Analysis Paper (due date) = ___________________(20pts)
*Participation
= ____________________(15pts)
GRADE:
100 pts possible
Distance Contest
Joule Mobile Evaluation – Rubric
PRE-LOOK PICTURE (5pts)
2 PERFORMANCES = 2 RACE DAYS
PERFORMANCE (distance traveled)
10+ meters day 1 = 10pts / day 2 =20pts
9+ meters  day 1 = 9pts / day 2 = 18pts
8+meters day 1 = 8pts / day 2 = 16pts
7+meters day 1 = 7pts / day 2= 14pts
6+meters day 1 = 6pts / day 2 = 12pts
5+meters day 1 = 5pts / day 2 = 10pts
4+meters day 1 =4pts / day 2= 8pts
3+meters day 1 = 3pts / day 2 = 6pts

PHYSICS ANAYLSIS
Conceptual Analysis
Practical Analysis (experiment)
Each Member will answer following questions – MUST BE TYPED: (20pts)
1. Explain ALL the energy transformations in your joule mobile.
2. What problem(s) did you encounter and how did you adjust for this?
3. How did friction play a role in this project? Name as many frictional areas in the mobile as you
can, and include the type of friction. How did you reduce the friction? Was there any wanted
“good” friction? If yes, where?
4. What changes did you make from the first race day to the second race day?
5. Explain the scientific method process that you (or your group) encountered during this project.
6. Describe your participation in the project (what did you do?). Describe what your partner or other
help did on this project.
