Initially, the value of vi is greater than the term (-gt) and the body moves up. However, with the passage of time, when ’t’ increases the term ‘gt’ also increases. At a certain time vi and ‘gt’ will be equal and vf = 0. This would be the highest point of the motion.
Earth still attracts the body with the same force and acceleration. After this moment, the body changes direction (reverses) and now moves downward with the same acceleration.
Hence, it is possible for a body to reverse its direction when the acceleration is constant.
MashaAllah
