How Does Gravity Influence Spring Potential Energy in Physics?

AI Thread Summary
Gravity continuously affects a mass even after it impacts a spring, influencing the spring's potential energy. The discussion emphasizes the importance of considering gravitational forces in energy calculations. Participants noted that energy conservation principles should be applied throughout the process, rather than focusing solely on impact speed. Clarifications were made regarding posting guidelines, specifically about using images appropriately. Ultimately, incorporating gravity into the calculations led to the correct results.

Homework Statement
The weight is falling from a height of 1 meter. Then it touches a spring and it contracts. The weight of a body is 2 kg and k of the spring is 100 N/m.
1) What's the maximum contraction of the spring
The answer is supposed to be 0.852m(I got 0.392m)
Relevant Equations
E=1/2kx2

Your writing is not clear enough to be posting as images. Forum rules request you only use images for book extracts and diagrams.
Did you take into account that gravity does not stop acting when the mass hits the spring?
You do not need to find the impact speed. Just work with energy, end to end.

Thank you, I didn't put gravity to my equation. After I did, I got the right result.

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...
