Multiplechoice questions may continue on the next column or page – find all choices before answering. 001 (part 1 of 9) 10.0 points What happens to the total energy of the mass spring system as time increases? 1. It monotonically decreases. 2. It monotonically increases. 3. It oscillates. 4. It remains constant. correct Explanation: 002 (part 2 of 9) 10.0 points At what point in the mass’s trajectory is the kinetic energy a maximum? 1. only at the lowest point 2. at the springmass’s equilibrium position only on the way up 3. only at the highest point 4. at both the highest and lowest points 5. at the springmass’s equilibrium position only on the way down 6. at the springmass’s equilibrium position on the way up and down correct Explanation: 003 (part 3 of 9) 10.0 points At what point in the mass’s trajectory is the kinetic energy a minimum? 1. only at the highest point 2. at the springmass’s equilibrium position on the way up and down 3. at both the highest and lowest points correct 4. at the springmass’s equilibrium position only on the way up 5. only at the lowest point 6. at the springmass’s equilibrium position only on the way down Explanation: 004 (part 4 of 9) 10.0 points At what point in the mass’s trajectory is the potential energy a maximum? 1. at the springmass’s equilibrium position only on the way down 2. at the springmass’s equilibrium position only on the way up 3. at the springmass’s equilibrium position on the way up and down 4. at both the highest and lowest points correct 5. only at the lowest point 6. only at the highest point Explanation: 005 (part 5 of 9) 10.0 points At what point in the mass’s trajectory is the potential energy a minimum? 1. at the springmass’s equilibrium position only on the way down 2. at both the highest and lowest points 3. at the springmass’s equilibrium position only on the way up 4. only at the lowest point 5. at the springmass’s equilibrium position on the way up and down correct pasha (sep635) – Model 3 Reflection – Antoniewicz – (56445)...
