When an object enters the atmosphere it burns up from compression, not friction.

For example when a meteor enters the atmosphere the meteor is heating up due to air compression not friction. If the meteor is made of oxidizable material and as it heats up from the compression then you see the meteor burn up.
It’s the same principle behind fire pistons:
I thought it was friction all this time until a physics video popped up on my YouTube feed.

Yep. The system (meteor) is doing work (compression) on the surroundings (atmosphere).

That’s honestly fascinating. Thanks for sharing.

Physics is real. Birds are not.

Isn’t the friction causing the compression?

What if it's a big thicc rock? I like 'em a little meteor

I’m just irritated that I’ve been told it was due to friction my entire life and never questioned it.

Well...

The honest answer is IDK. But I can speculate. The friction enables compression to occur but most of the heat is coming from compression. It’s likely a combination of both but compression is likely the biggest contributor to the total heat gained .

Confused.
Doesn’t the meteor break up due to outer layers being worn away?
Enters as a basketball but ends up as a golf ball or not even making it to the earths surface?

Only if the meteor is made of oxidizable materiel like iron. When iron gets red hot it oxidizes quickly. That’s why the space shuttle is covered in non-oxidizable ceramic tiles.

This is from a NASA website

Have you ever seen a meteor shower, where meteors burn up and streak across the sky? Some people call them shooting stars. Those meteors are burning up in the mesosphere. The meteors make it through the exosphere and thermosphere without much trouble because those layers don’t have much air. But when they hit the mesosphere, there are enough gases to cause friction and create heat.

Durr durr it burns up cuz it hits the firrmermennmrnent!

Creating meteorite hoax to perpetuate space fiction and hide flat earth
1) call fire in the sky meteorites that burned
2) call empty holes like sinkholes meteor craters. Find any rock whatsoever around crater and call it meteorite
3) call the 5-10 pieces of small indiscernible airplane debris whose impact is witnessed per year meteorites
4) call military weapons testing meteorites

I’m going with compression. It just makes more sense.

What you’re seeing is not smoke, or burning particles. As a meteoroid (the actual solid chunk of material) blasts through the atmosphere, it violently compresses the air, heating it up hugely (note this isn’t due to friction, but compression; like when a bicycle pump heats up as you use it). The heat is so intense it ionizes the gases, stripping electrons from their parent atoms. As the electrons slowly recombine with the atoms, they emit light—this is how neon signs glow, as well as giant star-forming nebulae in space.
