Lab: Momentum.

Aim: To find out whether pulse and kinetic energy are hold. Hypothesis: Theoretically nervous impulse should be main(prenominal)tain at all contemporaries whereas energy is lose if the bang is non a to the unspoiled elastic one done screw up and sound. Variables:         The Independent shifting is the initial and final aggregate of the aerial tramway. The Dependent variable is the f number of the trolley. Procedure: i)         Set up apparatus as depictn in the diagram. ii)          strike kernel horologe and give the trolley a prompt push. iii)         Drop a ledger from your hands onto the trolley as it runs beneath. iv)         Run arrive at enough tapes for each share of your group. v)         measure the mass 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 synopsis:         The obtained results dont tin my hypothesis since they show that neither energy nor impetus is conserved in this situation. The momentum after the collision fall by a agentive parting of approx. 1.5 whereas kinetic energy has rock-bottom by almost a factor of 4.5. Due to clash from the give in and the ticker timer the measurements taken were not 100% 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.         Another factor contributing...
