Where is the Least Net Force on a Roller Coaster Going Through a Vertical Loop?

AI Thread Summary
The least net force on a roller coaster going through a vertical loop occurs at the top of the loop due to the balance of gravitational and centripetal forces. While the sides may seem to have less force, the principles of circular motion indicate that the top is where riders experience the least weight. This is influenced by the gravitational field acting on the coaster. Understanding these forces is crucial for solving the problem accurately. The discussion emphasizes the importance of applying physics principles rather than guessing.

Homework Statement



A roller coaster goes through a vertical loop, the net force on the coaster is the least, where?

Homework Equations





The Attempt at a Solution



I said on the sides.

however it could be at the bottom, at the top, or the same all the way around.

i assumed not much force is affecting the sides.
any help please?

So your strategy for solving the problem is guessing? How about applying some principles of physics instead? What do you know about circular motion? What forces are required to keep an object in circular motion? There's the answer to your question right there.

EDIT: As berkeman pointed out, this object is also under the influence of a gravitational field, and that factors in too.
 
You're just guessing. Think about it more. Where do the people feel the least amount of weight? (the pressing of themselves into the seat)
 

Thread 'Rolling without slipping on a curved surface'

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 '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...

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...
