Golf Ball 70,000fps 150mph

Slow motion of a golf ball hitting a steel plate at 150mph shot at 70,000fps.
Reminds me of a Peter Randall-Page sculpture at the end.

Playback occurs at 25 frames per second (or occasionally other speeds, but we'll us 25).

If you film at 25 fps and play it back you get real time footage.

If you film at 1 fps and play it back, every second of footage covers 25 seconds of real time - the footage will appear sped up by 25 times.

If you film at 100 fps, it will take four seconds to play back every second of real time - this is slow motion.

At 70,000 fps, every second of footage takes almost 47 minutes to play back.

no. that's not true. that's impossible!

Non-standard golf ball... Plain and simple. Golf balls deform, but not this much. I teach college physics. Some of you need to take my class.... Hehe

looks kile a strawberry at 0:13

why did i read the comments i was all happy when i watched the video now im annoyed

[LordSammyfoxy]

Is this a video or a scientific discussion forum lol

@kindofmagicmike Ok I think it's time to agree to disagree at this point. You're reaching.. Sure, ok, it's possible that the ball in the real video could have totally flattened like a pancake, warped like a water balloon, turned into an egg, and then returned back to a realistic shape in the split second this video could have covered since it's 7 times faster. Keeping in mind the ball in this video hit an obviously unstable surface and it still turned into a water balloon. Perfectly reasonable.

@kindofmagicmike "...the force acted on the ball from the club is more than 1.5x the speed of the club." Makes plenty of sense. If the club is going at 120 mph, the ball has at least 180 mph of force acted upon it depending on the club. But, this doesn't matter because now you're trying to tell me that the obviously real golf ball in my example isn't valid... I mean, come on man. I'm pretty sure they would have mentioned if there were any abnormalities before crunching it.

@Nixmix24

agreed, the ball appears to move at about 2/3 the speed it originally hit the plate with, and since the plate doesn't return to its original position some energy is lost, HOWEVER: this doesn't mean this video is fake, as the video you posted of the driver hitting a golf ball was taken at a MUCH (1/7) lower frame rate than this, so not only is the force on the ball much less, but some of the warping is not recorded, making it perfectly reasonable that the videos appear different.

"You're not taking into account the fact that the force acted on the ball from the club is more than 1.5x the speed of the club." this statement makes no sense (the rest of your post does) and i still doubt your authority to say that the ball must shatter, as the ball in the video you posted could very well be a ball with a different tensile strength, plasticity, and even temperature than the one in this video. even glass can bend and warp surprisingly in short time frames.

@kindofmagicmike Also, and this is VERY important, you would be more accurate at your 300 mph mark if the wall was solid like a brick wall where the ball would be taking on nearly all of the forces acted upon it since the wall wouldn't have any give. Watch this video again and you will see that the wall moves significantly thus absorbing quite a bit of the forces. This brings your number much closer to my previously mentioned number of 1.5x the speed of the club.

@kindofmagicmike You're not taking into account the fact that the force acted on the ball from the club is more than 1.5x the speed of the club. I'm not saying that the force isn't greater in this video, I'm saying that it's close enough that the ball would act similarly in the 2 videos. I'm sure the ball would warp more in this situation, but not to the point that it would flatten out. You're also ignoring the fact that if it did have the speed to warp like this, it would break.
