14lb/more revs vs 15lb/less revs?

[billf]

Here's a question lol
If a true free arm swing just uses gravity and momentum, how does a lighter ball go down the lane faster? Why wouldn't the heavier ball go faster given the gravitational pull would be stronger?

I'll just say this: You can throw a 14 pound ball faster than a 15 pound and leave Newtonian Physics and such to others. Which I see billf has done.

I'm trying to avoid throwing the ball.

I hate being wrong so I'm doing more research :P

I haven't met anyone yet that liked being wrong yet. Some just handle it better than others, but I'm not one of them :P

It probably depends on gravity more than weight because a guy once dropped a large object and a small object (the large object was heavier). They landed on the ground at the exact same time. "

Technically, an object with more mass would have a higher gravitational pull. The only problem is, the weight is the balls aren't different enough for it to be relevant.

Wow......now we need to start DR. BILL, PHD LOL

I said before I'm a science geek. My specialty is Quantum Physics. The hard part is putting it in terms everyone can grasp instead of just using formulas most people don't recognize.

Correct, mass not actual size determines the gravitational pull. Gravitational pull is what determines weight (on Earth with no vacuum). The point being though is no matter the pull or size, objects fall at the same rate when the friction from air is removed. The larger object would naturally create more friction from dispersing a higher volume of air.

In my many years of coaching, I can tell you one way to judge this. Many times bowlers with good strength, throwing a lighter ball will over throw the ball. In other words sometimes, actually many times, a little more weight will stabilize a persons swing plane. I see it all the time with younger players, and all you have to do is move them up a pound or two. A lighter ball allows more speed and revs, this is true, but the arm swing will also be able to pull the ball easier, too.

If you can throw throw a 15 and not experience any discomfort, I'd say stick with that. Remember you're rolling that ball against over 35#'s of pins. Advantage.....15 #'s !

At the ideal weight you will control the ball, not the ball control you. Also you want to be able to roll the ball with the correct timing. Too light and it will be thrown, too heavy and you can't control it. Too heavy and the end timing is usually too early, too light and it ends up late. This happens because when it's too light you have a tendency to muscle it more trying to create more speed and revs. Muscling the ball actually causes the swing to slow down a few thousandths of a second.

I can tell you this much. My lil bro uses 14, and I use 15. His ball deflects alot more than mine, I've seen shots of his that would have been strikes if it was 15 pounds. But if you can't throw it with accuracy, there is no point in having a heavier ball.
