Force of air resistance on projectile

Can anyone explain this to me, please?

Force of air resistance is not dependent on the mass of the projectile, but a heavier projectile will go farther because it will add inertia, which increases the force required to change its motion?

How does this compare to this understanding?

I thought that heavier projectile will have less flight time and less range because its initial vertical velocity will be lower due to heavier mass... if you think about kicking a bowling ball versus a tennis ball...

I guess it might be a compromise... but I don't clearly understand how air resistance relates to inertia, if at all...

Think about throwing a piece of paper and a tennis ball with the same amount of force. Which will will go farther? The tennis ball or a piece of paper?

I think the tennis ball with go farther because it is has more mass which means it has a greater tendency to resist change in it motion.

Air resistance acts on an object to ****** its motion. As a projectile passes through air, air molecules collide with the projectile and slow the projectile down. Both the amount of air molecules that are hitting the projectile and the speed at which the air molecules are hitting the projectile tend to slow down the projectile.

So the two qualities that tend to increase air resistance for a projectile are its speed and surface area.

The faster that a projectile moves the more air resistance it experiences because the molecules are hitting it faster.

The greater the surface area of the project the more space it has avaliable for the air molecules to hit the projectile.
