Golf Ball hitting steel super slo mo

@arltheman 9 years ago

I teach physics. Golf balls are fairly elastic -- they bounce pretty high on a hard surface as the rebound speed is usually a bit less than the impact speed. They will deform in a high-speed collision, but not this much. This is a fake golf ball -- maybe foam or rubber. Question everything you see, especially online!

It is a closed cell foam rubber golf ball. They come with kid's toy golf sets. They are very squishy! It's still a very cool video even though it is not a real golf ball.

Apparently this is a practice golf ball. Not what they use in the real game

I used to have a golf ball that looked exactly like that. It was made of a soft rubbery closed cell foam. It came with my son's little plastic golf set.

Blatantly a fake. If you look at the various other slow motion golf Ball vids you'll see that none of them distort like this. There is SOME distortion, typically the edge being struck will flatten but only about a fifth of the entire golf balls size. The rest of the ball will take a slight oval shape and then quickly returns to its normal shape as the elastic properties of the ball propel it forward.

To help reduce some of the arguing, I don't know if anyone else has mentioned this, but if you take into consideration the speeds involved, it makes this very interesting: 70,000fps and the ball traveling 150mph -- to be honest, I'm somewhat surprised the ball doesn't shatter on impact (maybe some brands do? - something for Mythbusters perhaps?)

"TAKE TWO!!" *hits the camera* FUUUUUUUUUUUUH-

@ChapterGrim i thought impulse was the change in acceleration? wouldn't this be something more along the lines of reformative ability?

@badbass9 I've disassembled several different kinds of golf balls, and it only reinforces the fact that the above is exactly what would happen. What exactly were you referring to as being problematic? Was it the malleable plastic cover? The malleable hardened rubber coating? Or the interior entirely made of rubber thread that you find impossible to believe would do the above?

@LostPie depends what composition is that particular plastic; could be a derivate or mixed with a more flexible plastic,with elastic properties. think about it,if you think that golf balls were to break when hitting steel like in the video then ... wouldn't they break first when hit with the golf club ??

@sorak185 How many frames per second is this, then?

@shadowofthewarriors 12 years ago

@Inquisitor32 that is why golf balls are made at higher strengths at higher levels of golf... they are hit harder so are harder to compress as much. and it is also the time spent in compression that makes follow through so crucial.

@MalcolmCooks 12 years ago

And that, is why golf balls bounce so well.

Ironically, pretty much everyone saying to 'Take a physics class!11!1' clearly hasn't taken a physics class

@gunnerdelta Did it occur to you that it might have been shot out of something rather than hit with a golf club? I mean it is pretty perfectly centered in on the camera view

@nebbit1 Druckversuch 2 shows a golf ball being compressed over a long period of time in such a way that there is a sharp corner pressing into the ball by the time it breaks.
