Fill in the observation chart and then provide sample calculations for either 'E2 or '12. You mav nd it impossible to calculate him for explosive interacb'ons. Sample Observations Chart Svnlh esis Questions 1. In some collisionsr'interactions. the total momentum was zero before. during and after the collisioni'interaction. vet the total kinetic energy did not remain constant. Use this observation to explain whi,r it is important to distinguish between scalar and vector quantities when analvting conservation of momentum and conservation of energv. 2. How could the results of this investigation he applied to determine the mass of a sealed refuse bag on board the International Space Station. {The I55 is in constant free fall around the Earth}. To realll.r explain vour answer. drainI a diagram. include some sample numbers etc. room is El m long. astronaut has a known mass of so kg. stopwatch times of and show how vou would calculate the mass of the refuse igarbagei bag. 3. If we added adjustable friction pads to the carts how would this have affected the results of the Investigation? Imagine small little brakes adding a few Newtons of friction force before. during and after the collisionnteraction. Conclusion: 'g 1I-Iv'rite one based on the results and hvpotheses. Pyuu Lab Estimation of Momentum Purpose: To observe the law of conservation of momentum during one dimensional interactions: elastic collisions. inelastic collisions and explosions. - - - - - - - - - _. ,_ Hypothesis: The heat lossi'gain during an 55 m a} elastic collision will be negligible Q s - sis of hi. _ Bi inelastic collision will be signicant Q a- 29% of hi. Ci exploslye interaction will be signicant :1 H D J. Procedure ' In class use the dynamics carts which mass around 1 kg with some brass masses. Some carts haye a spring for elastic and explosive interacb'ons. Some carts haye 1lielcro for inelastic interactions. Mass the carts to nd the exact masses for more accurate lab results. ' If at home then use the Physics Classroom simulator l WW5; Interacyeo'Momentu ma nd-Collisionstolli sionCa rtsr'CoIlisionCarE-Interactiye J. ' If in class or at home conduct two of each interaction mentioned above in the hypothesis. For each interaction do so once with two carts of equal mass [on approitimatetyr 1 kg with 1 kg or 2 kg with 2 kg you pick}. then once with one cart more massive than the other by 1 to 3 kg [91L 1 kg with 4 kg or 5 kg with :5 kg you pick}.
