With what acceleration does the body thrown upward move? How is it directed?

When the body is thrown upwards, it is given a certain initial velocity equal to V. From this moment, only the downward gravity will act on the body. It will impart to the body an acceleration g equal to 9.8 m / s ^ 2, also directed downward. This acceleration is constant for any body, in the conditions of the planet Earth. That is, the movement of any body up after a throw is a slow motion, since the acceleration of free fall decreases its speed until it reaches 0, and the body begins to fall down.
