In free fall and projectile motion: If the initial velocity starts by going down(free fall) or horizontal(projectile motion) then the acceleration is positive? For equations of motion for constant acceleration? If the initial velocity starts by going up(free fall) or above the horizontal(projectile motion), the acceleration is negative?
