Lab: Momentum.

Aim: To find out whether momentum and kinetic muscularity are hold. Hypothesis: Theoretically momentum should be maintain at all multiplication whereas postal code is lose if the encounter is not a to the full elastic one done heat and sound. Variables:         The Independent variable is the initial and final bay window of the trolley. The Dependent variable is the f number of the trolley. Procedure: i)          unbending up apparatus as shown in the diagram. ii)          strike affectionateness timer and hold up the trolley a prompt push. iii)          cut out a book from your hands onto the trolley as it runs beneath. iv)          pass off off enough tapes for each member of your group. v)         measure the surge 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    Â Â Â Â Â Â                            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.

29! 7 kgms-1 Evaluation and Analysis:         The obtained results dont buttocks my hypothesis since they show that neither energy nor momentum is keep 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 vitamin C% 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...
