Conclusion 1. Discuss whether your results indicate that momentum was conserved during the completely inelastic collision between the ball and pendulum cage. Include numerical values during your discussion. 2. Was kinetic energy conserved during the collision? If not, mention 2 forms of energy that the lost kinetic energy was converted into. 3. Discuss whether the theoretical expression for percentage loss of kinetic energy has good agreement between the experimentally determined value. What does this imply regarding the assumption of conservation of momentum? Include numerical values during your discussion. Sources of Error1. Discuss experimental factors that may affect the values of v_i and Vf, (and therefore pi, pf, KEi, and KEf.) Consider all the measured values involved, and whether there are any unaccounted-for factors that could change those values (eg "outside" forces), and therefore change the calculated results of v_i, Vf, pi, pf, KEi, and KEf. 2. What was one external force present during the collision between the ball and pendulum cage? What does the existence of an external force during the collision imply regarding the assumption of conservation of momentum?.
