Rolling Rolling RollingProblem: Does the height of the ramp affect the distance a car travels?

HYPOTHESISIf we roll a toy car down ramps of different

heights and measure the distance it rolls, then we think the car on the highest ramp will roll the furthest

distance.

Procedure

Rolling Rolling RollingResultsUsing our data we collected, with calculators, the total distance of each ramp height, then got an average by dividing the total by the

number of trials, five for each height. See Data Table and Graph

Rolling Rolling RollingConclusionWe noticed that the more books we added to the ramp, thefurther the car traveled. The majority of the class predicted in the hypothesis that the twelve book ramp would travel the farthest distance. The fifteen students who voted for the twelve book ramp werecorrect.A ramp is an inclined plane, a simple machine , a tool that uses force to make work easier.We believe that the raised height did some of the work and made it easier for the car to move and move farther.
