AI Thread Summary
The discussion centers on two statements regarding acceleration and kinetic force. The first statement suggests that if one object is accelerating, another must also be accelerating, which is deemed false since an object can accelerate independently without interacting with others. The second statement posits that a stationary object can exert a kinetic force, which is also considered false because a stationary object has zero acceleration and thus exerts no net force. Questions arise about the definitions of kinetic force and the implications of Newton's Third Law in these contexts. Overall, the conversation highlights the nuances of acceleration and force in physics.

Homework Statement



1) If one object is accelerating, there must be another object that is accelerating (T/F/N)
2) A stationary object can exert a kinetic force. (T/F/N)


Homework Equations


2) F=ma


The Attempt at a Solution


1) My answer is false for this one because if the object doesn't interact with any other objects it won't cause any acceleration to other objects. (I learned that Δp=-Δp. If I divide both side by Δt, I will get F=-F. Assuming masses are constant, there are changes in acceleration?)
2) My answer is also false for this one since stationary object has zero acceleration, all the forces sum up to zero also. (If you pushes an object on a floor, would the floor exert a kinetic friction on the box when it's stationary?)

1. If an object doesn't interact, does it accelerate? Think of Newton's Third Law.
2. What is a kinetic force? I've never heard this term before.
 
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...
