Lab: Momentum.

Aim: To find out whether momentum and kinetic faculty are hold. Hypothesis: Theoretically momentum should be keep at all multiplication whereas verve is lose if the concussion is not a to the full elastic one by heat and sound. Variables:         The Independent variable is the initial and final mess hall of the trolley. The Dependent variable is the f number of the trolley. Procedure: i)          heap up apparatus as shown in the diagram. ii)          strike heart timer and accomplish the trolley a prompt push. iii)          spend a book from your hands onto the trolley as it runs beneath. iv)          hand off enough tapes for each member of your group. v)         measure the hatful of your book and the trolley. Results:         mtrolley = 805g ± 10g mbook = 845g ± 10g Ticker timer goes at 50Hz = 1/50s = 0.02s vi = di / ?t                                     vf = d2 / ?t di = 5.4cm ± 0.1cm                           vi = 0.54ms-1 d2 = 1.8cm ± 0.1cm                           vf = 0.18ms-1 Ek = mv2 / 2 Ek before = 0.117369 J Ek after = 0.02673 J Pbefore = Pafter Pbefore = mv                                             Pbefore = 0.4347 kgms-1         Pafter = (m + m)v                                    Pafter = 0.

297 kgms-1 Evaluation and Analysis:!         The obtained results dont canister shot my hypothesis since they show that neither energy nor momentum is hold in this situation. The momentum after the collision decreased by a agentive role of approx. 1.5 whereas kinetic energy has decreased by almost a factor of 4.5. Due to friction from the give in and the ticker timer the measurements taken were not blow% accurate. clangor was the main cause of inaccuracy in this experiment.         Kinetic energy is lost in this experiment and has been transformed into heat and sound.          some other factor contributing...
