加速度 here shouldn't be confused with the compound word "加速" (accelerate/ acceleration)

加 = add

速度 = speed

加速度 = add speed.

The difference between "acceleration" and "adding speed" is clear, acceleration means "speeding up", which means things have to be in motion already

"add speed" means " move things along at a higher speed" It could mean things have not been moving along or moving at a languid pace since the beginning
