Force magnitude from acceleration vs. mass graph?

AI Thread Summary
To find the magnitude of a force from an acceleration vs. mass graph, it's important to understand that the relationship is defined by Newton's Second Law, F=ma. The graph typically shows how different masses respond to the same force, resulting in varying accelerations. Replotting the data as acceleration vs. 1/mass can help clarify the relationship. This allows for the determination of the force by analyzing the slope of the new graph. Understanding this concept is crucial for solving related physics problems effectively.

I am a new university physics student doing some homework, but i cannot find the method for this problem.

How do I find the magnitude of a force from an acceleration vs. mass graph?

I know mass is the inverse of the slope of an acceleration vs. force graph, but I'm not sure how to do this the other way around.

Any help?
Thank you !

Your question makes no sense. If you are plotting acceleration vs. mass, you must be plotting the response of numerous different objects (having different masses) and being subject to some forces, leading to some accelerations, possibly different for each of the different objects.

I would replot acceleration vs 1/mass.

yes. it may be multiple objects, but there is only 1 force acting on them. I'm assigned to find the magnitude of that force.

"The following figure shows the acceleration of objects of different mass that experience the same force."
"What is the magnitude of the force? "

how would that let me find the magnitude of the force?

We just started this chapter and I guess the book assumes you know how to find the magnitude from the graph. I don't know how to do that.

Use Newton's Second Law.
 

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...
