I'm doing this experiment in physics laboratory (I) about projectile motion and I'm concerned about some of the results (range) I'm getting. I'm using spherical projectiles about 3.0 cm wide (diameter).
Here's the thing, with the launch angle from 10 to 20 (thus, from 80 to 70) I'm getting everything as the theory predicts.
However, when I launch it at 45 (max range) or even 40/50 I get a maximized range but I get deviations of the balls in the y axis, meaning that |Δy|>0 (and not ≠0 as it should be).
I've asked my professor and even suggested the cause of it being the aerodynamics of the balls along with the friction force but he denied it and didn't give me a straight fulfilling answer.
The Attempt at a Solution
My 'theory' about these deviations is that the farther a ball travels, the more time it's subjected to the friction force (obvious) and so, along with variations of pressure (due to its movement) the ball is forced to deflect (rotate) to the left or right. Again, I'm not sure this is true.
I could really use some feedback from you guys :tongue:
