-- In the absence of air resistance, the object's diameter has no effect

at all on the projectile motion.

-- In the presence of air resistance, one has to know everything about

the object AND the air in order to have a prayer of calculating the effect.

Q: What is the effect on the projectile motion when the diameter of the object is changed?

-- 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.

They are the same, if the effect of air resistance is ignored.

hypothesis on projectile motion

Because a projectile by definition, is in motion.

Projectile motion has two components horizontal motion and vertical motion. Gravity affects only the vertical motion of projectile motion.

A feather falling in a vacuum is not considered as a projectile motion. Gravity, which is absent in a vacuum, is one of the components of projectile motion.
