In which case the mass has hardly increased so the force isn't substantially different either. Article says ball is 16oz, roughly 450 grams. It gains according to you 2-3grams. Or 0.5% in percentage terms.I’m aware that heavier things take more energy to move, but as the articles above point out, they didn’t actually absorb much water, certainly not a bucketful. According to one of those articles they soaked an old-style leather ball in water and it gained 2-3 grams. Even with my knackered legs that wouldn’t make much difference.
I know we all ‘seem to remember’ them being heavy, but apparently not.
“An enduring myth”.
And is still offset by even that slightest decrease in speed due to the slight increase in weight.
I'll admit I was surprised the weight hasn't changed. I sued to have an old fashioned style ball of leather with laces on and it was massively heavier than the more modern one. I admit it wasn't a professional ball and we never weighed them to see but that old one really took some wellying to get any power behind the shot. Newer one a casual swing would get it travelling faster easy.
To use a golf analogy I needed the driver for the older one, but only a 7-iron for the new.
