Question

1. students push a toy car across three different surfaces using the same force each time. they measure how far the car rolls before stopping. the data are shown in the table. on which surface did the car experience the most friction? tile floor, because it has a smooth surface tile floor, because the car rolled the farthest carpet, because friction prevented the car from rolling as far wood floor, because all hard surfaces transfer the same amount of energy

Explanation:

Friction is a force that opposes motion. A greater amount of friction will cause an object to stop moving more quickly. In this experiment, the students used the same force to push the toy car each time. The distance the car rolled before stopping is an indication of the amount of friction. The shorter the distance, the more friction there was. The carpet surface had the shortest distance (0.8 units). This means that friction on the carpet was the greatest as it prevented the car from rolling as far as on the other surfaces.

Answer:

Carpet, because friction prevented the car from rolling as far.
