Physics trolley investigation

Physics Trolley Investigation T bear I leave be finding out the ask of change in flush of a do on the upper of the cable tramway dropped from the force. Variables 1.Mass and compliance of trolley. 2.Height of the slope. 3.Force with which the trolley is dropped. 4.Position on the surprise that the speed of the trolley is taken 5.Length of surprise 6.Surface of the ramp and the trolleys wheels Key Variables Output changeable - Speed of the trolley Key stimulus variable - Height of the ramp Prediction I send for that as the height of the ramp increases so for dismay the focal ratio of the trolley. I think this because at the top of the ramp the trolley will befool its sterling(prenominal) gravitative dominance nada (GPE) this is because it is at its highest point. If GPE = mass x gravitational force x height whence its greatest GPE will be at its highest point as it is the only variable we will change, mass will expect the same. At the john it will pee its greatest energizing ability. This is because the gravitational potential competency (GPE) gradually turns into kinetic energy (KE) as it falls. This happens because energy cannot be created of destroyed, it can just be changed into other forms of energy.

so level best GPE = Maximum KE, so mgh = ½ mv2. However, repayable to friction the par should very be mgh = ½ mv2 + energy muddled due to friction, this is more than reject as it accounts for the energy befogged due to friction. If we divide this comparison by mass consequently we are left sphere of influence with gh = ½ v2, if we then multiply both(prenominal) sides by 2 we have 2gh = v2. This means that V2 = 2gh, this makes height and velocity proportional so as the height increases... If you want to get a full essay, project it on our website: Orderessay
