Golf Balls, not quite as hard as once thought

This is a normal golf ball hitting a steel plate, Amazing how much these things warp. its an insanely high speed, high quality camera, but still really cool

Holy crap, thats awsome.... Seeing how much damage our golf ball cannons inflict on our targets, imagine how much damage a projectile the same size and weight of a golf ball but harder, would do?

Is there any data on the velocity of the impact? I'm looking at using golf balls as part of a bumper in a future higher energy design.

In searching related videos, that ball appears to have been in the 150 MPH speed shot at 70,000 frames/sec. A more normal speed impact looks like this. It has much less ball distortion.

150 MPH is a little faster than your average drive.

I'm guessing this isn't your video but I'm not sure. If it isn't what source it it from?

To me it doesn't seem real... Think about how much it looks like a ball of water. It seems like a golf ball wouldn't look that liquid like. It would be more springy than flow-y...

[Lockednloaded]

Its not my video, but it was shot at 70,000 fps, and the ball was going 150 mph

[deathbyDWV]

150 mph isn't even as fast as a paintball gun shoots. I just think it's really unlikely that it's a real golf ball but I could very well be mistaken.

[Gun Freak]

DeathbyDWV, I know you have a HSC so why don't you try getting a video of a GB impact? I wouldn't be as fast but if you're lucky you may see the distortion of the golf ball....

[Lockednloaded]

well 70,000 frames per second is an pretty high quality camera, this might not even be visable to consumer video cameras

[Gun Freak]

Yeah you're right, but if you're lucky you may get a frame where the ball is getting smashed against the wall...

I don't think a normal golf ball can take that much distortion. Here is a video of a golf ball on a hydaulic press. It pops with less distortion shown in the video.

that may be a result of the press having a smaller diameter than the golf ball and not letting it "splay" out.

[psycix]

I think the ball is indeed softer than a normal ball, and I think it has a liquid core.
Are you sure that 150 mph is correct?
Maybe someone could count frames and see how fast the ball was really going, assuming an average golfball size.

Yeah that can't be a regulation golfball, i cut open one with a hacksaw to see what was inside and i found a rock solid, plastic type thing that smelt strongly of chemicals. But i have taken others apart to find the have a bouncy ball wrapped in about 10m of thin rubber band. (I like throwing them and watching them unravel in the air

Also, on a program called "How It's Made" it shows how they are made which is pretty cool.

To me it looks like a rubber casing with a liquid inside, as this acts in the same way as water balloons do when the are dropped but do not pop.

I don't think a normal golf ball can take that much distortion.

At high speeds, things can react very differently.

If you will, take a grape and a piece of corrugated cardboard. Press the grape into the cardboard, and the grape'll turn into a sticky mess. Fire it at the cardboard at a couple of hundred miles an hour and it'll put a hole through the cardboard. Crushing and an impact are not equivalent.

As far as that golfball footage, it's BBC sports footage, so I'd be surprised if it weren't a regulation golfball. The BBC are unlikely to have much reason to film non-regulation golfballs.

it reminds me of the jelly scope
