Jay, you can't go to a different frame to assess whether energy has been 
taken away from the source frame. This is what Poutnik is trying to 
explain -- energy is not expected to be the same in different frames. It 
never has been.

Take even a basic example. A child throws a 1 kg apple at his brother 
inside a moving car at 2 m/s. Let's look at this in the frame of the 
source: the child's frame. The apple has a kinetic energy of (1/2)(1 
kg)(2 m/s)^2 = 2 J. But now let's look at this very same apple in the 
frame of someone standing on the street, with the car going by at 20 
m/s. Now the kinetic energy of the apple is (1/2)(1 kg)(22 m/s)^2 = 242 
J. Now, did the observer on the street add 240 J to the apple? No.

So how is it that 242 J vs. 2 J doesn't violate energy conservation? 
What's your answer to that question?
