Answer: No. According to the Law of Conservation of Energy, energy cannot be created or destroyed. A machine cannot produce more work output than the work put into it.
Worksheets associated with Section 14.3 typically feature word problems requiring you to solve for IMA, AMA, or Efficiency. Below are standard examples modeled after typical curriculum textbook answer keys. Sample Problem 1: Calculating IMA Answer: No
Solution: AMA = Load / Effort = 500 N / 125 N = 4 IMA = Effort distance / Load distance = 6 m / 1.5 m = 4 Efficiency = (AMA / IMA) × 100% = (4 / 4) × 100% = 100% (This suggests an ideal, frictionless pulley system, which is theoretically possible but not practically achievable.)
