What effect does gravity have on the horizontal velocity of the projectile? Explain. 2. What effect does air resistance have on the range of the projectile? 3. Since there really is air friction in the experiment but you assumed there wasn't any, do you think that you over- or under-estimated the initial speed of your projectile? Explain
