Which law is involved in the concept that greater load results in less acceleration?

Which law is involved in the concept that greater load results in less acceleration?

• A. Inertia
• B. Gravity
• C. Acceleration
• D. Action/Reaction

Answer: (C)

The concept tested is that for a given net force, increasing the load (mass) reduces acceleration. This is captured by Newton’s second law, F = m a, so with a constant force, a = F/m. In rotorcraft terms, if you add weight, the same thrust produces a smaller change in speed or climb rate because the aircraft has more inertia and resists acceleration more. Inertia is the property that makes heavier masses harder to accelerate, which is why the heavier the load, the less acceleration you get for the same applied force. Gravity isn’t what sets this relationship, and acceleration isn’t a law itself but the result described by Newton’s second law, while action/reaction concerns forces between bodies rather than how mass affects acceleration.
