Physics Trolley Investigation Task I will be finding out the affect of change in height of a ramp on the velocity of the trolley dropped from the ramp. Variables 1.Mass and shape of trolley. 2.Height of the ramp. 3.Force with which the trolley is dropped. 4.Position on the ramp that the speed of the trolley is taken 5.Length of ramp 6.Surface of the ramp and the trolleys wheels Key Variables Output variable - Speed of …showed first 75 words of 1692 total…

…showed last 75 words of 1692 total…than 5 heights to improve my accuracy. I would try and make sure that the trolley is dropped straight every time and doesn't touch the walls or light gate on the way down as this affected some of my results. I would also decide a margin that if the results for one height are too far apart then the ones that are different should be taken again as something was obviously not fair on those results
