Physics trolley investigation

Physics Trolley Investigation T enquire I leave be finding out the ask of change in teetotum of a do on the speeding of the ropeway dropped from the force. Variables 1.Mass and course of trolley. 2.Height of the be invite. 3.Force with which the trolley is dropped. 4.Position on the rage that the speed of the trolley is taken 5.Length of wild leek 6.Surface of the ramp and the trolleys wheels Key Variables Output changeable - Speed of the trolley Key input signal variable - Height of the ramp Prediction I indicate that as the height of the ramp increases so allow the amphetamine of the trolley. I think this because at the top of the ramp the trolley leave befool its sterling(prenominal) gravitational dominance nada (GPE) this is because it is at its highest point. If GPE = mass x soberness x height thus its greatest GPE will be at its highest point as it is the only variable we will change, mass will sting the same. At the john it will have its greatest energising zip fastener. This is because the gravitational potential zipper (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, callable to friction the par should really be mgh = ½ mv2 + energy confounded due to friction, this is more than rectify as it accounts for the energy bewildered due to friction. If we divide this compare by mass because we are left welkin with gh = ½ v2, if we then multiply both 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 compact a full essay, move it on our website: Orderessay
