What is projectile downward inclined plane, upward inclined plane?

Upward acting projectile is the one when you throw the ball from ground and the downward acting projectile is when you throw the after going to certain height. Both make trajectories.

Now, distance traveled in a parallel (i.e, when downward projectile) will be more than the distance traveled when thrown from the ground (i.e, upward projectile) while in flight.

What is upward incline plane? What is downward inclined plane?

In case of upward projection, object is moving against the gravity i.e. we can say velocity has to overcome the gravity for motion, but in case of downward motion the situation is totally opposite.

As we know that horizontal component of velocity remain the same during projectile but vertical component changes in case of upward motion vertical component is decreasing (to overcome velocity) casing the resultant velocity to decrease.

During downward projection from inclined plane, range=horizontal range from ground+some value.

During upward projection, range=horizontal range from ground-some value.

In case of downward direction gravity helps to velocity weather the upward direction gravitational force opposes the moving velocity.

That's why the range of projectile on a downward inclined plane is MORE THAN the range on upward inclined plane for the same velocity of projection and angle of projection.
