![]() ![]() ![]() When you increase velocity it increases momentum. Question: When starting a heavy train, why will train engineers sometimes back up, stop, and then proceed forward? (This technique is called “bunching slack”.)Īnswer: The objective is to gain momentum using force you used before. Question: Nylon ropes stretch considerably under tension and are favored by mountain climbers because the ropes So if it takes more time to hit something then it would hurt less based on force being less. Question: Why are padded dashboards safer than hard dashboards in automobilesĪnswer: In terms of impulse, FT=P, the more F the less time, since they’re inverse. An empty boxcar, coasting at 3 m/s, strikes a loaded car that is stationary, and the cars couple together. In a railroad yard, a train is being assembled. ![]() Mass is again inverse to acceleration meaning the less mass the greater the acceleration. ©Modeling Instruction AMTA 2013 1 U9 Momentum ws 3 v3.1 Name Date Pd Impulsive Force Model Worksheet 3: Conservation of Momentum I 1. Question: Which vehicle will experience the greater acceleration?Īnswer: The Beetle because F/M=a. Impulsive force model worksheet 1 qualitative impulse momentumMomentum and collisions worksheet answers physics classroom Momentum worksheet impulse change ampPhysics with coach t: momentum review worksheet key. P/M=V, mass is inverse to velocity so the less mass, the faster. Basic impulse example on conservation of momentum worksheet. Question: Which vehicle will experience the greater change in momentum? Justify your answer.Īnswer: The Beetle because it has less mass which means it goes faster. Old cannons were built on wheeled carts, both to facilitate. The cars will both exert an action/reaction force onto each other. Which vehicle will experience the greater force of impact? Justify your answer.Īnswer: The force of impact will be the same for both based on Newton’s 3rd Law- action reaction. Question: A Hummer and a VW Beetle traveling at equal speeds have a head-on collision. The ball that bounces has a GREATER change in momentum being that the numerical value is larger. Question: Which has the greater change in momentum, a 50 gram clay ball that strikes a wall at 1 m/s and sticks or a 50 gram superball that strikes a wall at 1 m/s and bounces away from the wall at 8.0 m/s? Explain? Newton’s first law says that there’s not enough friction to stop/turn you. Impulsive conservation worksheet force model momentumPhysics form 4 form5: spm trial mara 2010 paper 2 ( impulsive force ) Impulsive force model worksheet 1 qualitative impulse momentumConservation of momentum and impulsive force worksheets w/ answers. Will you roll backwards if you go through the motions of throwing the ball, but hold on to it instead? Explain your reasoning.Īnswer: You’ll go forward because your roller skates stay in motion. Question: If you throw a ball horizontally while standing on roller skates, you roll backwards. ![]()
