Stephen Hawking Professor Stephen Hawking was a prominent scientist, known for his work in black holes, his discoveries made him a Nobel Prize winner, he proved that the universe follows the general theory of relativity. As a young man he caught ALS and was eventually confined to a wheelchair, but that didn't stop him from making ground breaking discoveries "Intelligence is the ability to adapt to change." "I have noticed even people who claim everything is predestined, and that we can do nothing to change it, look before they cross the road." "

Intro ...Rubber band cars are perfect examples of how friction, and elastic energy effect a vehicle, each component plays a pivotal role in using each force/energy  and moving the vehicle. Build Quality What to do ...Make an even and sturdy frame, make sure the dimensions of the parts are proportional, so the axels can be strait and the wheels wont turn. My Results (and mistakes) ...I made my frame out of straws and sticks sticking through the straws holding it together, and had four hole-punched construction paper pieces to hold the axels. My mistake with this design was at the beginning, the sticks were uneven making the axels turn, even though I improved the frame by adjusting the straws, but it still was a little crooked. Physics ...Making sure the frame is sturdy helps it overcome the forces acting on it while moving, as well as that having the right weight is necessary to keeping the right amount of friction to stay on the ground....
