Physics trolley investigation

Physics Trolley Investigation Task I add be finding out the ask of change in height of a do on the velocity of the tram dropped from the force. Variables 1.Mass and shape of aerial tramway. 2. vertex 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 opalescent - Speed of the trolley Key stimulation changeable - Height of the ramp Prediction I predict that as the height of the ramp increases so bequeath the velocity of the trolley. I call up this because at the top of the ramp the trolley will consume 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 lav it will have its greatest kinetic aptitude. This is because the gravitational authorisation 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 tell apart this equation by mass then we are unexpended field with gh = ½ v2, if we then multiply both sides by 2 we have 2gh = v2. This means that V2 = 2gh, this make s height and velocity proportional so as the! height increases... If you want to get a wide of the mark essay, roam it on our website: BestEssayCheap.com
