simple machines Trial # of Marbles Resistance Force (weight of Marbles) Effort Distance Resistance Distance Work Done Actual MA 5 50 20 N 25 cm 10 cm J 2.5 5 50 20 N 25 cm 13 cm J 1.9 5 50 20 N 25 cm 15 cm J 1.7 Students were exploring simple machines. In this part of the lab they were investigating the amount of work done when moving a load of marbles up an inclined plane. They used a spring scale to pull marbles up the ramp and recorded the data in the chart. By lengthening the resistance distance (making the ramp higher) what happens to the amount of work done to get the marbles to the top of the ramp? By lengthening the resistance distance the amount of work increases. By lengthening the resistance distance the amount of work decreases. The amount of work done is the same regardless of the resistance distance. none of these
