Why are bowling balls so heavy?

Question

What are they made of? What kind of stone or material?

Answer 1

the original bowling balls that you find in the actual alley are typically a hard plastic. the more expensive balls are made out of a material called polyurethane. they are alot better. they grip the lanes better and hit the pins harder.

Answer 2

actually, they aren't necessarily heavy -- some weigh as little as 8 pounds. regardless of weight though, nearly all of them are the same size. the reason why is simple enough -- so the ball return will reliably return your ball after being thrown. as far as the being heavy though, it is a simple matter of physics. the heavier ball will carry a given amount of inerita the length of the lane easier without giving up as much of it to things like friction on the lane & wind. it will of course also deliver more impact energy to a greater number of pins, since each pins impact will affect the ball less due to the heavy balls greater weight. imagine a train hitting several automobiles on the tracks (plows right through them) ...... then imagine someone on a bicycle trying to do the same thing (bike bounces off the first car, which btw only barely moves).

btw - many balls feature special "cores" (a seperate "ball within a ball" so to speak) which are intended to offer different things like higher impact energy transfer, and/or more rotational mass (ball keeps rolling further due to the majority of its mass being near the surface of the ball, & thus it having more angular momentum). some of the expen$ive ones can be downright technical.

Answer 3

the pin are heavy they would knock over that is why when the pins are smaller the bowling balls will be smaller

Answer 4

so they can knock over the heavy pins

Answer 5

To knock down all those pins! Plastic!

Answer 6

I dunno why but this just turned me on :|

just kidding... They are made heavy to hit the heavy pins and provide good muscles =-|
