Undergrad Understanding q: Lambda & S in the Equation

Click For Summary
SUMMARY

The formula q = λ ⋅ S ⋅ ∪_x represents the relationship between heat transfer and thermal conductivity. In this context, λ is identified as the coefficient of thermal conductivity, while S denotes the surface area through which heat is transferred. This equation is crucial for understanding heat flux in materials, particularly in applications involving heating rods. The discussion emphasizes the importance of precise definitions and context to avoid ambiguity in thermal conductivity formulas.

Unknown formula
What is this formula?
q=λ⋅S⋅∪_x
What does s and lambda mean?

Could be potential times vacuum permittivity times surface equals charge (electromagnetic field between to plates).
 
I know that this formula is related to the heating of the rod and the heat flux.
In this case, can λ be the coefficient of thermal conductivity, and s is the surface area through which heat passes?

Sure. But without any description it remains guesswork. Thermal conductivity has plenty of similar formulas, see https://en.wikipedia.org/wiki/Thermal_conductivity

Thread 'Does acceleration affect impact energy vs constant velocity?'

I do not have a good working knowledge of physics yet. I tried to piece this together but after researching this, I couldn’t figure out the correct laws of physics to combine to develop a formula to answer this question. Ex. 1 - A moving object impacts a static object at a constant velocity. Ex. 2 - A moving object impacts a static object at the same velocity but is accelerating at the moment of impact. Assuming the mass of the objects is the same and the velocity at the moment of impact...
