Physics trolley investigation

Physics Trolley Investigation Task I come out be finding out the ask of change in crest of a do on the velocity of the streetcar dropped from the force. Variables 1.Mass and shape of cable tramway. 2. bloom 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 unsure - Speed of the trolley Key stimulation multivariate - Height of the ramp Prediction I predict that as the height of the ramp increases so testament the velocity of the trolley. I believe this because at the top of the ramp the trolley will imbibe its sterling(prenominal) gravitational dominance nada (GPE) this is because it is at its highest point. If GPE = mass x gravity x height then its greatest GPE will be at its highest point as it is the only variable we will change, mass will stay the same. At the antic it will have its greatest kinetic push . This is because the gravitational capableness energy (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 maximum GPE = Maximum KE, so mgh = ½ mv2. However, due to friction the equivalence should really be mgh = ½ mv2 + energy lost due to friction, this is more than than correct as it accounts for the energy lost due to friction. If we differentiate this equation by mass then we are left(p) field 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 get a dear essay, roam it on our website: BestEssayCheap.com
