If the object is thrown upwards, the vertical acceleration is negative and the horizontal acceleration is zero.
-- The only horizontal force on a thrown ball is the force of air resistance, so the horizontal acceleration is very small, and the horizontal speed stays almost constant. -- The vertical force on a thrown ball is the force of gravity, so the ball accelerates straight down at the acceleration of gravity. -- The result of unequal horizontal and vertical components of acceleration is a curved path.
-- Gravity causes the vertical component of projectile motion to vary according to the local acceleration of gravity. -- Gravity has no effect at all on the horizontal component of projectile motion.
Gravity must be the only force acting on the object, to produce downwards vertical acceleration. There is no force acting in the horizontal direction because there is no acceleration.
Because gravity is acting on the vertical component, exerting a constant -9.8m/s2 worth of acceleration.

Horizontal and vertical components which need to be treated independently from each other when working out either the horizontal or vertical motion.

Projectile motion has two components horizontal motion and vertical motion. Gravity affects only the vertical motion of projectile motion.
Divide the motion into a horizontal and a vertical component. The horizontal component won't be affected by gravity. The vertical component will get a downward acceleration of 9.8 meters per second per second.
You need to know about gravity, forces, velocity, acceleration, and vector.
Gravity must be the only force acting on the object, to produce downwards vertical acceleration. There is no force acting in the horizontal direction because there is no acceleration.
Because gravity is acting on the vertical component, exerting a constant -9.8m/s2 worth of acceleration.

The vertical motion is accelerated downwards, at a rate of about 9.8 meters per square second. The horizontal motion is not affected. This all assumes that air resistance is insignificant, and can therefore be ignored.
Unbalanced force of gravity will not have any effect on horizontal component but makes a variation in the vertical component
Ceilings and floors are generally horizontal relative to gravity, whereas walls are vertical.
