i had to do a lab report with horizontal / vertical motions - projectile.... you know make a ramp throw a ball and predict where it's going to hit and place a can that place....
I'm working on my lab report, and I'm not getting this question:
3. Your probably noticed the range of the ball increased in direct porportion to the speed at which it left the ramp. The speed depends on the release point of the ball on the ramp. WHAT ROLE DO YOU THINK air resistance** HAD IN THIS EXPERIMENT?
what the hell does that mean?
and.. no i'm not going to say don't be rude w/ negative comments... b/c it's simple if you don't want to answer or if its not worth a minute of your time .... DO US ALL A FAVOR AND CLICK OUT OF THIS QUESTION.... Gracias!

When you did the experiment you'll probably notice that the actual results won't match up to the calculated results.
What Q3 is probably asking you is how air resistance effected the actual result in relation to the expected result. Air resistance is often ignored when calculating projectile motion. Was the difference in expected results enough to convince you that air resistance had a significant part to play? Air resistance should reduce the range that the ball is able to go. Was this evident from the results?
Was the ball of a shape, weight and texture to enable it to be smooth through the air, or was it fluffy and light so would be easily affected travelling through the air?

Hi. Air resistance would impact the ball in a couple of ways. If the ball was fuzzy, say a tennis ball, the turbulence woulds slow the ball before and after the bounce. Ir the ball was large and light, like a beach ball, the the same effects would be more noticeable. But your teacher is trying to impress on you that the air resistance increases as the speed increases.

Probably a ton of reasons but air has density related to humidity. simple answer is drier air has less density and puts less "obstructing force" or resistance on the ball therefore it goes farther. highly humid or "heavier" air puts greater resistance on the ball and it doesn't go as far. Air has weight which is related to it's density. Picture this....in drier or "light" air the ball is perfectly round, touching the ramp very little. When the air is "heavier" the ball looks like a water balloon, kinda mushed out and touches the ramp a lot which slows it down and it doesn't go as far. hope this helps.

WHAT ROLE DOES AIR RESISTANCE HAVE IN THE EXPERIMENT?
"Air resistance is less important than the momentum of the ball."
