Investigating the speed of a spherical object on a slope.

... Year 10 GCSE Practical Assessment Physics Plan Investigating the speed of a spherical object on a slope Variables The following is a list of variables that I could change in my experiment. I may vary: * Material of slope (e.g. the ramp could be wood, metal or plastic) * Friction of slope (e.g. the ramp could have water on it or ridges) * Colour of slope (e.g. the ramp could be blue, red or green) * Size of slope (e.g. the ramp may have a small width across or length from top to bottom) * Temperature of slope (e.g. the ramp could be at room temperature or at lower temperature) * Height of slope (e.g. the ramp could be at 70cm from a surface or 20cm) * Angle of slope (e.g. the ramp could be at 90 degrees or 40 degrees from a surface) * Length of measurement (e.g. the spherical objects speed could be measured over 1m or 0.5m) * Material of
