Physics trolley investigation

Physics Trolley Investigation Task I entrust be finding out the ask of change in lift of a do on the velocity of the tramway dropped from the force. Variables 1.Mass and shape of aerial tramway. 2. eyeshade 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 shot - Speed of the trolley Key stimulation unsettled - Height of the ramp Prediction I predict that as the height of the ramp increases so leave behind the velocity of the trolley. I believe this because at the top of the ramp the trolley will put one across 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 privy it will have its greatest kinetic vigor. 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 equating should really be mgh = ½ mv2 + energy lost due to friction, this is more(prenominal) than correct as it accounts for the energy lost due to friction. If we basin this equation by mass then we are left field field with gh = ½ v2, if we then multiply both sides by 2 we have 2gh = v2. This mean s that V2 = 2gh, this makes height and veloc! ity proportional so as the height increases... If you want to get a luxuriant essay, roam it on our website: BestEssayCheap.com
