How Does Air Density, Speed, and Cross-Sectional Area Affect Resistive Force?

AI Thread Summary
The discussion focuses on the formula for resistive force, which incorporates air density, speed, and cross-sectional area, highlighting their significance in determining air resistance. Key concepts include aerodynamics, drag coefficient, and terminal speed, which are interconnected and crucial for understanding how vehicles like cars and airplanes interact with air. The importance of these factors is emphasized in real-world applications, affecting performance and efficiency. Additionally, there is a side conversation regarding academic integrity, with a participant reprimanding another for attempting to cheat on an assignment. The thread underscores the necessity of independent research in grasping complex physical principles.

I'm looking for the formula for resistive force that involves "air density, speed of object, and cross-sectional area." I also need to know why it is an important factor in determinging air resistance, and include aerodynamics, drag coefficient, and terminal speed-how they relate to one another. Also how these play out in real life as in cars and airplanes.

-PLEASE ANY WEB SIGHT OF HELP YOU CAN GIVE IS APPRECIATED, beucase this is due soon! :rolleyes:

CamDaBballer11, I am fully aware you go to Heritage High and am also quite aware of young students who choose to abuse the internet for completion of assignments. My assignment was not to ask someone for the answer, it was to independently research the topic and to come to your own conclusions. You will be receiving a failing grade for the quarter and I expect a written apology and explanation on my desk next week.

There is no excuse for deliberately disobeying my directions and attempting to cheat. And yes, I do know who you are due to student information sheets and IP logs. Do not attempt to circumvent your punishment, you are already in enough trouble.
 
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
