Where does its kinetic energy go when it slows down?
The answer is that the ball has two types of energy
- The kinetic energy due to its speed.
- The gravitational potential energy due to the Earth's gravitational field. It is this that Bjarne is ignorant of.
As the ball gets higher it loses kinetic energy and gains potential energy. When the ball drops it gains kinetic energy and loses potential energy.

Try to freeze time and
point at the
ENERGY LOST exactly at the moons apogee.
We are talking about MASS / KE that is no longer there at apogee.
Towards apogee KE and mass disappears.
That the moon gets it back when it falls don’t answer the question where that energy was at apogee.
I mean
- was it hanging in the blue air
- inside the particles
- inside the Moon
?? WHERE ?
Point ? ( at ENERGY)
It is the same that I say there is a potential cow in you house.
The problem is that I can’t point at it, or decide what room the cow really is because you have still not bought it.
If a supernova explodes near the moon and it never comes back the energy is LOST.
And that’s the end of the story.
Of course we can speculate how the gravity process works and HOW the moon
possible can get that the LOST energy “back”.
But this is a different story and something that happens LATER.
Or we could speculate what when the Moon would be blown to almost to hell (by a supernova) but right before it was suck into a black hole, the speed would increased to 250.000 km/s and therefore relative to the black hole the Moon now have 1.000.000.000 more potential energy.
But still I MUST ask WHERE is the cow (Edith:
energy right N O W).
(Notice how close NOW and COW is to each other. )
Can’t you see it
Gravitational potential energy is an expression for a progress that still has not happens, it will MAYBE (most likely) happen LATER.
But until then there are no energy (and no cow).
(There is a MAYBE, - the moon gets that energy back)
BUT the real KE is LOST – at apogee.
Exactly like RC’s potential cow first will arrive tomorrow. - LATER
IF the cow NOT will arrive because RC has drunk away his money, and not pay it, there are no cows in that house (also not for the Myon).
Most likely he will get that cow, but a potential cow is not a real cow and it can also not replace a real cow.
Every farmer (and cow) knows that.
So the solution is:
that "we" (not me) can say that the KE due to speed is not real energy because the potential energy also not is.
And then we have exported that problem (too) the big blue junkyard as well.
Imaging the Moon was an energy bomb, - would a total explosion be less powerful at apogee. ?
Second question:
How big explosions can the Moons potential energy cause?
Now show me you are man / scientist and not mother's darlings, and ANSWER THAT QUESTIONS.
