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.

@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).

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

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

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.

While moving upward gravitational force restricts the motion of the body on the other hand, while moving downward gravitational force help the body to move downward.
So with force range of projectile (body projected at a target with particular force, force for both upward and downward motion is same) increases.

It is so because work is done align with the action of gravity.

I think only velocity changes but not range. Distance remains same.

I think answer is option B because of for example a stone you through in upward direction while coming return it will be more speed as you all know this simple technique thank you all.

When projectile moves upward its velocity reduce because negative gravitational acceleration there for time increase to reach same height but time taken to reach the ground less due to ground. And distance (range) = v/t.
As t increases d reduce &t reduce d increase. There for distance (range) inversely proportional to time.
As t increases d reduce &t reduce d increase. There for distance (range) inversely proportional to time.
