Bullet Block Experiment

Jinx says...

Essentially my guess is that the bullet can only transfer so much kinetic energy to accelerate the block upwards. Above that threshold it finds other ways of disposing of this energy. Why this threshold/diminishing return might exist idk.

So yeah, I think there must be some change in the efficiency of the transfer of energy in the two examples. Does smacking the bullet right in the centre create more sound? Does the bullet deform/heat up more in the first example because the block simple can't get out of the way fast enough? You'd think that spinning a block would take comparitively little energy compared to all those other inefficiencies. Perhaps if you were to increase the velocity of the bullet you might not see that large of a difference in the height it rises - rather the block would sustain more damage, the slug would pancake more etc etc.

It does seem raher counter-intuitive though. I'd like to know the explanation.

Now I want pancakes again. Crepes I find use too much dishes and are not superior unless there is Whipped Cream involved, which I have non of.

ENTHUSIASTIC Crepe maker!!

The world's fastest pancake maker?

I said that stuff as well.

I also remember eating pancakes at the church once or twice a year, apparently it is called Shrov Tuesday or something.. I just liked the pancakes...they were memorable pancakes, also the 50 litre Mcdonalds orange drink decanters. Singing "Thank you lord for bringing us life " and other songs. The church tried to get me.. I went to a catholic school because it was close ( I think that is the reason) and I broke free when I learned to rationalize.

Then I changed, it is okay to change. That mom is in serious denial.
