Hello and welcome to digital tea with mr.
00:03
E, where we will see what's brewing in the world of physics solutions.
00:08
So, james jewell, who the unit of energy is named after, expected to find a difference in temperature from the top and bottom of a waterfall based off of his energy analysis.
00:21
And the question is why? well, if we do an analysis of this waterfall and we consider what types of energies the water has at the top, we will see that there's both potential energy and there's kinetic energy at top of the waterfall.
00:40
And then the water tumbles over and it crashes on the ground down below.
00:47
And we can see that the river is moving at approximately the same speed above the waterfall and below the waterfall.
00:54
So it has k .e.
00:55
Again, and it's only k .e.
00:57
In this case.
00:59
So since the p .e.
01:00
Is gone, something must have happened.
01:02
Must have turned into heat.
01:05
So he would then predict that there should be an increase in temperature because heat was added to the water as it crashed into the rocks below at the bottom of the waterfall.
01:17
So if you take a look at conservation of energy then, we can say that the energy at the top of the waterfall should be equal to the energy at the bottom of the waterfall...
