Question: Sentence 1: In machines that increase force, such as ramps and doorknobs and nutcrackers, output is greater is the relation between output and input force. Sentence 2: There is on-going research to develop general models that relate electrical inputs (voltage, current) to mechanical outputs (force, velocity) and vice-versa.

Answer:
neutral
