Morphology
motion + with + variable + acceleration
The phrase's meaning is directly compositional: a learner who knows 'motion', 'with', 'variable', and 'acceleration' can infer it denotes movement whose acceleration changes over time. The structure follows ordinary English noun + prepositional modifier patterns and is cross-linguistically regular, so a B1 learner would readily understand it from its parts.
Etymology
Motion with variable acceleration uses motion meaning movement, variable meaning changing, and acceleration meaning how quickly speed changes. Think of a car going over hills or a swing that gets pushed harder and then softer; the speed changes unevenly, so the phrase means 'acceleration is not constant'.
