The two types of friction that affect the performance of our car are static friction and kinetic friction. 2. We reduced the friction on the wheels by replacing them with rubber wheels. Rubber wheels have less friction than plastic or other kinds of wheels. There was friction on the string by the wood. We fixed this by making the string not touch the wood to avoid the friction. 3. We have four wheels; we decided that four wheels would move more smoothly than three. It also moves more likely to go straighter if it has 4 wheels. 4. We used rubber wheels, because they have less friction than other kinds of wheels. Using small wheels would make the car not travel as far; therefore, we used larger and heavier wheels. 5. Newton’s first law: the wheels will continue to spin after the mouse trap sets off, because of this law and that is how the car will keep moving forward. However, it will
