Question

When is acceleration due to gravity considered Positive and Negative why
​

Answer 1

hii 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

The acceleration due to gravity (g) is considered positive for objects which is coming downward because the g is acting in the direction of motion for such objects.

The g is considered negative for the objects traveling upwards because in such case the g is acting in the direction opposite to the direction of motion.
