interesting thing I read

hi golfinguy
you say that pushing onto a sink lets you weigh less on the scales but that dont make you lighter it only means you have not weight yourself as you are shifting some of the weight to the sink through your hands, you still weight the same. and in all my years in the army i never head if a technology that made us weigh less, and you talk about helicopters but the rotors produce lift in relation the the weight thats why helicopers cant carry much of a load.
i really dont see any way you can make yourself lighter swinging a golf club. your full weight will transfer from foot to foot but you cant have 25% of your weight on both feet and suddenly lose 50% of your weight swinging a golf club, even for a second.
your last point about the centrifigal force working when swinging dont make the club heaver, it did it would be impossable to change it direction of the club head when comming into the ball and to open and close the face through impact as you would be fighting that centrigal force and thats not the case as you can change the swing path when swinging. if swinging with a weighted club then it does get harder to change the swing plane but it still possable.
try using a power ball and when its spinning and swing your arm like you do with a golf club, then you will feel what centrifigal force feels like but it still dont make you lighter.
cheers
bill

Nothing changes it’s mass nor it’s weight. The direction and magnitude of the acceleration of things DOES change. That changes the force that your mass applies to the ground. When you are standing still the force you apply to the ground absolutely has to be equal to your weight. However, when you’re moving, and/or when you’re moving objects that you’re holding, the force you apply to the ground doesn’t have to equal your weight. Flex your knees and jump into the air. You’ve gone from applying a "50/50" force to the ground to a "0/0" force applied to the ground.

I’m not going to vouch for the specific percentages, 25/25 or whatever, because that seems a bit extreme.

bill reed, no offence but i am done trying to explain to you about this topic, you seem to be on a differnt page.

kpb, you got me, but i don't think 25/25 is too extreme, how much weight do you think it takes for you to lift on to your tippy toes?

I think it's a factor of the forward and upward momentum of the follow through that lifts upwards or even off the ground, the more violent (As with a long driver) the more momentum and subsequent lift.
