Easily Confused

accelerate vs speed up — Same idea; accelerate is the formal/technical word (used in physics, business, driving instruction), speed up is the everyday phrasal verb. You 'accelerate growth' in a report but 'speed things up' in conversation. The opposite of accelerate is decelerate (or 'slow down').
