Galileo's Incline plane.... Help for SAC. Hey everyone i am new here so excuse me if i confuse you all. I am currently undertaking Galileo's incline plane for my yr.12 assessment and i am a little lost with what i am trying to prove... the data i collected is as follows. - The volume of the 2 balls used - The length of the incline - The angle used - Weight of the beaker - Weight of the beaker after each trial run(once water was placed into the beaker during each trial.) I simply weighed the beaker. Then simultaneously i released the water clock and the ball to fall down the incline. Then i weighed the beaker after the water was collected after each run at full length, 3/4, 1/2 and 1/4. My problem lies in what im trying to figure out. I don't know what i should figure out.. Whether i should find acceleration.(But how would i find that..) Or whether i should prove the formula that distance is inversly proportional to time squared. Another thing that i have read on the net but don't understand is the theory that explains that: The difference in ratios of distance traveled is the distance in ratios of time squared.??? How can i find time with the weight and distance traveled that i have found from conducted my experiment? I also realise that i forgot 2 measure the mass of the 2 balls. Although one ball had a Volume of (3.4 * 10^-4) and the other was (4.1887* 10^-4) The heights of the incline are as follows. full - 84cm 3/4 - 63cm 1/2 - 42cm 1/4 - 21cm (The angle of the incline is 57 degrees although.. the results should be the same with any angle so i guess you can presume the angle is 60 degrees.) Any help is much appreciated and im sorry 2 give u all a head ache. THANKS.
