Planning: Aim The aim of this experiment is to show how the height of a ramp from which a trolley rolls down will affect its run off speed. Preliminary The preliminary experiment we did prior to the investigation enabled me to choose what factors of the investigation I should keep the same or alter. My results from the preliminary displayed that I should perform the following procedures: - ?óÔé¼?¥h The heights that allow the trolley to go down the ramp at a suitable velocity and whereabouts on the ramp I would allow the trolley to...
timing proved to be most accurate:

Height m Time using stopwatchs Time using tickertimer s

10 1.76 1.59

10 1.56 1.47

30 0.67 0.97

30 0.91 1.04

Prediction

I predict that the higher the ramp is the faster the speed of the trolley will be and the average velocity and time will not be directly proportional.

Due to gravitational potential energy GPE which is the amount of energy that an object has because it its position. The higher the object is the more GPE it has and my table below proves
