Question

HEY GUYS..
.
TELL ME IN WHICH SITUATION THE ACCELERATION DUE TO GRAVITY IS NEGATIVE..
.
PLEASE NO SPAMMING××××​

Answer 1

Any object affected only by gravity (a projectile or an object in free fall) has an acceleration of -9.81 m/s2, regardless of the direction. The acceleration is negative when going up because the speed is decreasing. The acceleration is negative when going down because it is moving in the negative direction, down

Answer 2

Generally, when an object is thrown upwards, the acceleration due to gravity in the upward phase of its flight is taken as negative.

Basically, during deceleration which occurs when you throw a ball upwards, before it accelerates back down.

But it really depends on which axis you take as positive and negative.
