Joel Engelsma LAB REPORT FOR FRICTION The purpose. We will see how friction affects the distance the car will travel by different surfaces. Hypothesis the car will travel on a smoother surface because there is less friction than on any other. Our independent variable is the different surfaces. The dependent variable is the distance the car will travel. Materials A toy car A board A yoga mat A tape measure A towel 4 books Procedure Step 1 put the car on the top of the board and layout yoga mat about under the slanted board. Step2 roll the car down the downward slant and measure how far it went. Step3 record the measurements on paper or computer. Data distance traveled Towel 11.5 inches 12 inches 13 inches Average 12 ⅙ inches Bare floor 113 inches 121.5 inches 118 inches Average 117.5 inches Yoga mat 27 inches 28 inches 30 inches Average 28 ⅓ Discussion and Results The ...
