I recently completed a lab using an online projectile simulator about the range of projectiles. I launched a projectile with different initial speeds (5 m/s, 10 m/s, 15 m/s, 20 m/s, and 25 m/s). For each trial, I did the launch with and without air resistance and I plotted Range (with Air Resistance) vs. Initial Speed and Range (without Air Resistance) vs. Initial Speed onto my calculator. The former graph was logarithmic and the latter graph was exponential. Why is this so? This has nothing to do with my homework; I just wanted to know.
