If an object's velocity changes from 2 meters per second to 6 meters per second in five seconds, its acceleration is calculated as follows:
62)/20 = 80m per second per second or or 80m per second squared (m/s2)

Scientists do their experimental tests more than once so they effects of chance errors.
