    Range Spin
AI Thread Summary
A ball thrown horizontally with a clockwise spin will experience a shortened range due to the Magnus effect. The Magnus effect causes a spinning ball to experience a force that alters its trajectory, affecting its distance traveled. The discussion highlights the need for specificity when comparing the range of a spinning ball to a non-spinning one. It emphasizes that the range is shortened relative to the scenario where no spin is applied. Understanding the Magnus effect is crucial for analyzing the impact of spin on a ball's flight.

Homework Statement



If a ball is thrown horizontally in a vertical plane with a clockwise spin, the range will be shortened. Is it true?


Homework Equations





The Attempt at a Solution



I guess it is false in accordance with Magnus effect.
 
Physics news on Phys.org
The range will be shortened compared to what? Be specific.

Tell us what you think the Magnus effect means.
 
Compared to the case in which any spin is not imparted.
Magnus effect is the phenomenon by which a spinning object in a fluid experiences a force perpendicular to its line of motion.
 
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 .
Thread 'Trying to understand the logic behind adding vectors with an angle between them'
My initial calculation was to subtract V1 from V2 to show that from the perspective of the second aircraft the first one is -300km/h. So i checked with ChatGPT and it said I cant just subtract them because I have an angle between them. So I dont understand the reasoning of it. Like why should a velocity be dependent on an angle? I was thinking about how it would look like if the planes where parallel to each other, and then how it look like if one is turning away and I dont see it. Since...
Thread 'Voltmeter readings for this circuit with switches'
TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...
