hi chaps, im doing this work on "investigating how the distance travelled by a ball bearing rolling down a slope affects the time taken" (i know riveting!! lol) and what ive got so far is a table of results (distance it rolled and then how long it took) ive also got : angle of inclination of ramp = 5 degrees mass of ball bearing = 16.7g diameter of ball bearing = 15.3mm and now basically ive got to do a various amount of equations im guessing to tell me lots of stuff!! but im not really sure what im susposed to be doing, i need a push to get me rolling (excuse the pun!!) so can anyone please help me!! thanks a lot, alex!
