Help a HS teacher understand uniform motion?

[William Ray]

Thanks. I agree. Apparently William Ray and Spinnor don't get the idea that, if you put a thermometer in a bucket of ice water, the temperature you measure will be 0C.

I'm not sure where you get the impression that I don't get that idea. I don't believe anyone's disagreeing with you that the surface of the ground will not exceed 0C. I also don't see why you think this is relevant to the question you asked. You are aware that the temperature of the air, (as well as the black-body temperature of the night sky, though it seems we're mostly ignoring radiation here), are significantly below 0C for much of the winter, in many parts of the world?

If you can find anything in what I've said that suggests that there is not an upper limit to the temperature that the sub-snow ground can attain, I'll eat my shorts. Otherwise I believe you're off base here.

I'm very sorry. Please forgive me. This is all my misinterpretation of what you were saying.

Delighted to hear it! I'd hate to think that one or the other of us had gone insane :-)

lol what of the blanket of snow keeping the ground cold,

Given "mother in laws" reasoning a thicker blanket would maintain the delta in temps better. I'm sure Canadian golf courses have plenty to say about snow blankets.

I would also imagine the average ground temp has a huge influence on this. I think it might be called "frost depth". The ground where I live is probably only frozen a couple of meters down at it's peak...now does the blanket maintain the frost or protect it from going deeper?

I’m confused. Is the snow blanket at rest, uniform motion, or non-uniform motion?
