Projectile Motion Concept Question

Hey guys I have a couple of questions on some concepts regarding projectile motion...

So I'm a bit confused as to whether or not an increase in the duration of flight time during an objects parabolic path increases the range. I've heard some differing statements on some of the TBR Physics passages that I've done and I would like a bit of clarification. So in one situation, if the air resistance were negligible, then an increase in the time flight would result in an increase in the range of the particle. However, when air resistance is taken into account, the time of flight then experiences no net change but the range of the particle decreases b/c air resistance is also acting in the x-direction of the velocity. Are the reasonings that I've just discussed correct? Thanks a lot guys!

This depends on what is being varied and what is being held constant. If you increase the time of flight by, say, increasing the initial velocity, then yes, you will also increase the range. If, however, you increase the time of flight by increasing only the initial angle, then no, you may not increase the range. Before we can discuss the impact of air resistance, we need to be clear on the basic question of what is being changed.

Range = horizontal velocity * time
