    Distance traveled
AI Thread Summary
The discussion centers on understanding the calculation of distance traveled during the nth second, which is derived by subtracting the distance covered in the first n-1 seconds from that of the first n seconds. This method highlights the specific distance an object travels in that particular second. There is skepticism about the necessity of this equation, especially considering its limitations with varying time units. The conversation reflects confusion over the relevance and application of this concept in physics. Overall, the distinction between the nth and (n-1) second is crucial for precise calculations in kinematics.

Homework Statement
I dont understand what this mean lol
Relevant Equations
S = S_o + v_o + \frac{1}{2}at^2

Hi! I don't understand why is made the difference between the n second and the (n - 1) second. Can anyone help me? Thanks!

The distance traveled in the nth second is the distance traveled in the first n seconds minus the distance traveled in the first n-1 seconds.
But why anyone would bother to develop such an equation (to be remembered?) is beyond me, especially since it breaks down if using different units for time.
 
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...
