Upward = -9.8 m/s^2
downward = + 9.8 m/s^2

When thrown upward, the object has an acceleration of -9.8m/s squared since it will gradually slow down and fall back towards the ground.

As an object free falls back down, the acceleration is 9.8m/s squared.
hope this helps

The acceleration upwards is determined by the force of which the object is launched with. Imagine a guy throw a ball directly upwards, it will accelerate with x m/s^2, whereas a cannon firing directly upwards will accelerate with y m/s^2. (x and y are variables) the cannon will have a larger acceleration than the guy.

A free falling object is subject to gravity 9.81 m/s (But it varies depending on where you are on earth) and it is a constant. There is no gravity in space, therefore you will experience weightlessness in space.

Whenever an object is in the air, the accelaration in 9.8m/s^2  downwards, doesn't matter whether its on its way upwards or downwards, this is considering that there are no other forces that affect the object
