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!
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.
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?)
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.
+II JEE lI There's a good chance you're wrong. 1.) The squash/stretch depends on the speed of the ball or the object that's hitting it, and of the hardness of that object; the shock is partially absorbed by the object smacking the ball. 2.) The freedom of each object to move also will influence the amount of squashing/stretching. You watched a ball get smacked by a club, but you forget that *both* are moving, and neither is tied down to one spot. In this situation, the impact target is for the most part stationary, and is rather hard (you can see that it only moves backwards, but doesn't distort), and it reflects nearly all of the force back into the ball. 3.) The speed of the camera is what determines just how much of that squashing/stretching you even see. Those other cameras are only at 22k fps, which gives the camera about *9-12* frames of the hit. This particular shot has at least a couple of hundred. This shot was taken with a MUCH faster camera with a MUCH harder impact than those you watched whereverelse.
It is a closed cell foam rubber ball. They come with kids plastic golf sets. They are a little bigger than a regular golf ball. Very squishy! It is still a very cool video even though it's not a real golf ball!
Hey, I'm a big fan of your most recent film: a game of shadows. The way in which you are able to solve mysteries is beyond me. The comment you have left on this video is no exception, this video had me scratching my head for years, thinking "how could a golf ball do that???" but then you come along and blow my mind with your powers of deduction... sleep well sweet prince.
Also, this video isn't a shot of a standard golf ball. The USGA released an official shot of a standard golf ball under the exact same circumstances, and it didn't compress nearly as much as this one.
@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.
@Inquisitor32 ok, the reason this happpens is forces. in the front of the ball, forces push backwards because of the wall. however, in the back of the ball, there is still the results of the force of the club pushing the ball forward. This causes the front to go back and back to push forwards, making the compression you see here. then it reverses direction once the net force becomes large enough to move the ball in the opposite direction.
@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 ??
@wasistdaswasdasist Yes but the hard outer shell cracked. If you look at this the outer shell remains unblemished. That is why people are calling it fake. It would crack under those stresses if it was a real golf ball. (well i'm thinking titanium core ones.)
Idk guys commenting "fake"... Everything has elasticity, and a golf ball certainly wouldn't maintain a perfect spherical shape after hitting the steel. Although you'd think if it was traveling fast enough the steel would dent and absorb some of the force. This video is probably stretching it, no pun intended.
@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.
the golf ball is a flexible plastic casig with a shitload of rubber in it, at the point it's almost flat however the plastic would break quite easily, golfers hit their balls into rocks and trees all the time and split balls real easily
I can't believe this is a real golf ball. Their inner core is a solid piece of rubber, and even at 150mph this sort of deformation seems impossibly "soft" looking, like it's from a bouncy ball that is capable of being squished in your hands. I mean, when you hit a golf ball the fact a prime component of hitting it is giving it spin, and this sort of deformation makes spin almost much less possible. If anything, the ball should have broken upon contact at this speed.
I know a bunch of people are saying that this isn't fake this is what really happens. But I don't believe it till they show themselves shooting the golf ball and they are a professional team like time warp. I know that everything warps on impact but this is just impossible. There is no way it can warp that much.
@R4wkFist You mean definitely. Maybe golf balls at a range because they tend to value quantity rather than quality. Most decent golf balls will have a rubber like centre. Ive ran over a fair few with a lawn mower.
@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?
Most balls now are not pure rubber cores. Higher level materials such as resins, and other polymers are used to reduce or increase spin depending on the shot. For example: The Callaway Hex Black Tour has a urethane cover(exact chemistry proprietary) 2 mantles of Surlyn® ionomer ethylene copolymers, and a 2 layer core system of polymer based resins. I think a purely rubber core inside a hard outer shell would cause the cover to crack and/or shatter on impact with a steel plate at these speeds
@wowelite2 false, titanium* isnt the strongest, it is light and strong as iron, also biocampatible, but not the strongest, also, there are golf balls whitout it.....
@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
@inviktus1983 Elastic objects really do deform like this if there's a high enough speed. You can actually see the energy transfer across the ball to the antipodal in a wave.
It's a squash ball or something like that, then made to look like a golf ball via software. A golf ball (even if it could be squashed flat) would not rebound like that, modern golf balls have very high CoR and they lose VERY little energy when something hits them. This balls wiggles and jiggles in the air after it hits the steel plate....losing so much energy. A golf ball hardly deforms at all when hit with a 120mph swing
not sure if it's fake or not, but i know this is what actually happens in real life, so it doesn't matter if it's fake, because it's still an accurate simulation...
actually it is totally possible because when you hit a golf ball you swing at no more than 110 mph so it would be like this ball hitting the wall at 110 mph. Also I have been doing some research into similar things and have got similar results with a Bridgestone e7 and a Titleist Pro V1x
@thepictureman007 The golf ball compresses in much the same way off of the clubface of a driver. However it is a lot less pronounced. My guess is they shot this ball out of some sort of air cannon at very high speed.
@Ghstwn "pwned" is a variation of the word "owned" often used in video games to taunt someone of whom you have just beaten in an extreme fashion. From my own experiences i have come to the conclusion that the variant word pwned (also spelled "powned") is the result of quickly trying to type while still playing the game which normally causes a 'Typo' so common between gamers that the varient is prefered over the original word as it has more humorous value. in this context, you 'pwned' him ;)
@Swimfreak44 you prolly dont realize the golfball was prolly fired by a machine too, a machines power can be limitless, although a humans power is VERY limited
first of all the ball is traveling at 150mph not 300. Second there is no difference if the ball is moving or the wall/club is moving. . Ask a bug that hits a windshield. Two masses are interacting with each other at 150mph period. MV=MV
@takematt It really isn't 'fella'. Look at the video 'Druckversuch 2'. This golf ball isn't one you'd find normally. The 'Druckversuch 2' is what would really happen, a regular ball wouldn't just bend and flow like in this video. Perhaps one would, but it's not one that would get you anywhere on a course.
@MOZZWIGAN Yes, but I think this ball is made of a much softer rubber than a real golf ball. There are other videos showing a real one and they do compress but only a little bit. If real ones did this then they would be unpredictable when hit with a club.
What do you have to shoot a golf ball out of to make it flex like that? Was it shot out of a giant cannon that uses a nuclear bomb instead of gunpowder to launch it?
@yo123454321 have u every seen what a golfball looks inside ? this is just a well done 3D animation . take a look at any other golfball video and u will c that this will not happen . not at 150mph. and no u have never studied a golfball or what so ever .
@inviktus1983 You don't need the origins of the video, you need a high school physics class. Golf balls are a rather malleable medium, and no collision is perfectly elastic. Should the ball hit something while going very fast, the momentum changed in the first parts of the ball to hit the wall do not affect the parts of the ball behind them, so there will be a part of the ball deforming onto the wall, some part bouncing back, and some still moving forward
have you ever played golf. oh right no. on the club face of a good player the ball compacts and they probably shot this out of an air cannon at super high speed. golf balls are meant to compact there not rocks. oh and btw this video was awesome
A professional golf swing is 100-120 mph. Tournament broadcasts usually show super slow-mo of the ball as it is struck. The ball does not behave like this. This is a fake.
