To Investigate the Factors which Determine the stopping Distance of Rollers down a Ramp Theory- When the roller is rolling down the slope then potential energy is converted to kinetic energy that converts into heat energy. MGH = 1/2MVsquared The loss of kinetic energy on the carpet is .... 1/2MVsquared = braking force x braking distance therefore.... 1/2Mvsquared = F x so MGH = F x If m, g and f are constant then.... However if G is constant then.... So.... This relation ship can be tested for a fixed angle, roller mass and fixed carpet. Predictions- In this experiment, before it was conducted and results were obtained , I predicted that for all the rollers, that the stopping distance would be directly proportional to the distance up the ramp. This prediction can be tested by plotting a graph of the results. Variables and Constants in the Experiment Variables Constants Distance up ramp Type of carpet Distance along carpet Angle 'G' Mass of roller Type of metal To maintain a fair test these are...
