Tips

usage

加速度 is the precise physics term - distinct from 速度 (sùdù, speed/velocity). It's also used metaphorically in news and business writing about anything 'gathering pace': 改革加速度 (reform's acceleration), 经济加速度 (economic acceleration). Built transparently: 加速 (accelerate) + 度 (degree) = 'rate of acceleration'.
