Investigating Ball Rolling Distances on Different Surfaces

This experiment explores which surface allows a marble to roll the farthest: cupboard liner, carpet, or carpet pad. The hypothesis is that the marble will travel the farthest on the carpet pad. A bicycle ramp was used to measure the distance the marble rolled on each surface after several trials. The results confirmed the hypothesis, showing that the marble rolled 71 inches on the carpet pad, highlighting the influence of surface texture on rolling distances. Recommendations for improving accuracy are provided to ensure consistent results in future experiments.

  1. As the Ball Rolls By: Ericka Parry

  2. Question: • On which surface will the ball roll the farthest? Cupboard Liner Carpet Carpet Pad

  3. Hypothesis: • My hypothesis is that the ball will roll farthest on the carpet pad.

  4. Materials: • Marble • Bicycle ramp • Carpet pad • Cupboard liner • Carpet • Measuring tape

  5. Safety: • Don’t start experiment without permission and supervision. I didn’t start the experiment until my mom said I could. • Clean up after the lab. I put the surfaces back in the basement and put the ramp back in the garage.

  6. Procedure: • Place carpet at the bottom of the ramp. • Set marble in the middle of the ramp and let it roll down. • Measure the distance the ball rolled from the bottom of the ramp. • Repeat four times. • Repeat steps 1-4 with the cupboard liner and the carpet pad.

  7. Variables: • Independent: The surfaces • Controlled: The ball that I use, the angle of the ramp.

  8. Data: Distance of Marble

  9. Conclusion: • In conclusion my hypothesis stated that the ball will roll the farthest on the carpet pad. My hypothesis was correct. According to the data the ball rolled the farthest on the carpet pad at 71 inches. Possible problems that might have occurred with this lab include; I might not have put the marble in the exact same spot every time. A solution to this is to mark the spot with a piece of tape. Another problem is the ball almost rolled off, a solution is to put up guard rails.
