Oiling pattern is up to the event organizer. Oil pattern is never uniform. The lane is 40 boards wide, each board 1 in wide, and 60 feet from foul line to the 1st pin. Oil is laid down from 4 inch after the foul line down to between 35 to 42 feet. Depending on the house, they may strip the...
The CoM of the pin is higher than the CoM of the ball. How much higher, I don't know. It depends on the manufacturer (they're allowed to have hollow space within the pin, the location, shape, volume is up to them).
Friction between lane and ball you can almost take out of the equation. In a...
Does more rotation of the bowling ball result in faster pin?
Here's my understanding, please check my physics.
The ball has 2 forms of energy, kinetic due to its momentum and rotational due to its angular momentum. When it hit the pin, there're transfer of energy. The pin will pick up...
Assumes the transfer of energy from the bowling ball to the 1st pin to be 35% (max allowed by USBC). Assumes the percentage energy transfer to be same regardless of the weight of the ball. Assumes energy loss due to noise/heat is negligible. Assumes the energy lost as the ball traverse the lane...
