Algodoo

Good job on reproducing the experiment with Algodoo but there are a few things that are not quite accurate, which may or may not affect the accuracy of the results. For one, a modern bullet is elongated, not spherical. For another (which was completely overlooked in Varitasium's video) is the fact that a bullet rotates on its axis at very high RPM due to the rifling in the gun barrel. That spinning of the bullet may have some effect on how the block of wood behaves while the bullet is penetrating it.

I would love to duplicate the experiment in "real life" but unfortunately, I no longer live in a rural area where I can shoot my guns as much as I wanted to. Now I live in a city where I would get arrested for discharging a firearm for no good reason. Anyhow, this is a very interesting physics experiment!

I never considered the spinning bullet, but since you mentioned it I noticed in the video that the center hit block rotates about the gun barrel axis. Another thing that is interesting about a spinning bullet is that spinning must reduce friction in the direction of penetration.

- Just use insanely long plank so leverage will be bigger
- Create progressively decreasing drag material, so bullet that goes deeper will have lower resistance so it will go futher exponencially...oh yeah, I'm replying into wrong page

So reply for you S_noonan:
Nice, I like videos like those, well done continue *MAKING SCIENE* (read in Glados voice)

Note:
I calculated something from physics and I made it in algodoo, results were EXACTLY THE SAME (forces on box with static and dynamic friction)
Who would know using algodoo as intended is great

Thanks. Now I can sing the "Making Science" song in my head when I make new scenes.

OMG, that song, Making Science, would give an aspirin a headache!
It's the worst "noise" I've ever heard. Even "Rap" doesn't sound so bad now!

s_noonan at it answering the real questions!

Xray
- So you never played a portal? Then google it's final song Cara mia
- I would advice you to listen to floppotron songs (floppy disc reader as musical instruments), that's what I'm calling a NOISE
