How to use 加速
加速 is used for vehicles and also for abstract processes like development, growth, or reform. It can take an object directly or stand alone. Example: 我们要加速项目的进度。(Wǒmen yào jiāsù xiàngmù de jìndù.) We need to speed up the project's progress.
加 (jiā) means to add, and 速 (sù) means speed, as in 速度 (sùdù). Add speed and you get 加速: to accelerate.
Common mistake: Learners sometimes say 加快速 or 加速度 when they mean to speed up. 加速度 (jiāsùdù) is actually a physics noun meaning acceleration, while the verb is just 加速 or 加快 (jiākuài).
