Question

In free fall, when do we consider that the acceleration due to gravity is positive and negative?

Answer 1

gravity acceleration is always in the same direction, but, relative to the ground, it is negative when the object is traveling upward and positive when it is traveling downwards.

Answer 2

grativy is a property og the earth to attract any mass to its center, therefore gravity is always downwards(positif) so when a mass is moving against garvity (upwards) the gravity is negatif
