Scientific Method 50 Points Denise conducted an investigation on the effect of friction on a toy car. Tennis had a ramp that he moved onto four different surfaces. During each trial, he rolled the toy car down the ramp and measured the distance the car traveled from the bottom of the ramp. He repeated the investigation three times on each surface. His data is shown in the table. Surface Distance (cm) Trial 1 Trial 2 Trial 3 Wood Black Top Gravel Sand Based on Denise’s results, what should he conclude The toy car rolled the greatest distance on the wood The toy car rolled the shortest distance on the gravel The toy car rolled farther on sand than on black top. The toy car rolled farther on gravel than on blacktop. See Answer
21
Answer: F. The toy car rolled the greatest distance on the wood.
