I have never disputed it, I used that calculation in the equations you seem to think are wrong. Why are you so insistent that I don't understand basic physics, when you can't even demonstrate why.

Your's and the others math was wrong because you merely subtracted the effect of gravity rather that subtracting it as a multiple as the equation implies..
1/6 gravity implies 1/6 force..Not a mere subtraction but a division..

We subtracted the force, not the gravity.
Earth:
F = m * 9.81
Moon:
F = m * 1.63
The resulting force already includes the effects of gravity, and these can happily be subtracted.
Which part of this don't you understand, and do I get an apology for your insults yet?

If you agree with F=MG then I was right in saying a ball 6 times heavier could be thrown with same force/velocity as a 6 times lighter ball on earth in a vertical throw..

See that's where you fail basic math..
You continually subtract when you should be dividing..
Does Weight not equal Mass X gravity ?? W=MG...

Haha oh my god you're still insulting me when you've just illustrated how little you know explicitly.
Yes, W=mg, F=ma, please tell me how you can throw something without imparting it with momentum.
I'll wait.
That's not true. Take a look at AS11-40-5921. Notice the radial striations under the engine:

No mate, I'll wait for you to explain why you are subtracting rather than dividing..
This force does not change if you accelerate the ball, it is always W=mg. Gravity has no place in F=ma, as you are modelling only the acceleration of the mass of the ball. The resulting force on the ball is W + F, Weight, plus the upward force applied to accelerate it. Nothing more.

Thanks for proving my point..

Seriously. the equation says it all..
It's 1/6....Not minus 1/6...
I'm really over this BS...
Prove me wrong..
The equations speak for themselves..

Who knows, or cares? They were throttling the engine down and began the shutoff process as the contact prongs hit the regolith. Whether they would have produced a crater if they had not throttled down is irrelevant, as they also would not have landed.
Damn relevant point that you wish to pass over without a definitive answer..
Transcripts show they did NOT turn the engines off till after landing..
Facts are facts, answer them...

I found alternate sources for the power of the LM engine at 4700N to 28000N. This is a measure of force rather than energy, and so taking the same assumption the force on the ground would be 4700N / 3120 in² or 1.5N/in², or about 0.33 psi.
Significantly lower than was estimated. This was also biased high.

All you did was state the opposite.
That is an answer not backed proof.
I asked if Cernan lied.
You have not answered that question.
Cernan said the LM would have made a crater.
Did he lie, yes or no?
