@All.

Let me explain. Imagine you are standing on an upward inclined plane. Now when you make a projectile, you will have to overcome the peak and thus it reduces your range.

But when you are standing on a downward inclined plane, then you will be able to throw at any projectile and thus you will get a larger range.

(Imagine yourself firing an artillery gun from a mountain).

r=2usin^2(theta)/g. Here denominator is g so the range is inversely proportional to g. On uphill g has more influence on projectile than downhill so its range decreases.

Because when it is down to top it experienced gravity thereby decreasing the velocity or the it speed.

Yes, the main reason is the gravitational force of the earth.

As the projectile travels through the air, the horizontal component of velocity remains constant, but the vertical component of velocity changes due to the effect of gravity, which pulls the projectile downward.

This results in the projectile travelling a greater horizontal distance before it hits the ground.

Upward force only one cosθ.
Downward forces are gravitational and sinθ.
