Third person singular present of accelerate; to increase in speed, rate, or amount; to cause something to happen sooner or faster.
From Latin acceleratus, from ad- (to) and celerare (to quicken), from celer (swift). The word entered English in the 16th century, initially meaning to hasten any process.
Einstein's famous equation E=mc² reveals that acceleration and gravity are actually the same phenomenon - you can't tell the difference between being in an accelerating elevator and standing in a gravitational field. This equivalence revolutionized our understanding of space and time!
