    Default Burning up energy

    I hear this phrase all of the time, usually in connection with the need to put away a strong ball and take something with a weaker/more polished coverstock out of the bag. What does it mean?

    That there is too much friction between the ball and the lane, which causes the ball to hook early, causing it to lose energy and roll out.

    When you make a shot, the ball goes through three stages Skid, Hook and Roll.(which is harder to see now a days, because the balls transition through the stages faster.

    Skid-
    Skid is when the ball is spinning (rotating) perpendicular to the direction of travel. Which causes the ball to hydroplane on the oil that's on the lane. Like a car tire sliding on wet pavement.

    During this period it is storing energy, to release it when it hits the dry. To make that hard turn and hit the pins hard.

    Hook-
    Is when the ball starts to come out of the oil and encounters the friction of the dry lane. It then stops skidding and starts to change direction and go into a forward roll toward the pins.

    This is when that energy starts to kick in, it's like spinning your car wheels. They spin till they get a grip on the road and the car takes off.

    Roll-
    Roll is when the ball is rolling parallel to the direction of travel, a forward roll. The energy is falling off and the ball starts slowing down.

    If the ball is too aggressive, the hook and roll will happen to early (Burn up). So by the time the ball hit the pins, it will have lost most of its energy and will carry weakly. Or it won't quite make the turn toward the pocket and leave a washout or something.

    That's the thing a lot of bowler's don't get. They think they are bowling on heavy oil because their ball isn't hooking and they want a stronger ball. But a lot of times they are bowling on a dryer shot and they need to use a weaker ball or one with more skid, so it retains energy longer.

    Heres a article talking about it also.
    Kegel white that talks about it also

    Here's a video example from the paper-( though I think there could be a better one)

    The only thing I'd pick at is the direction of rotation during the skid isn't necessarily perpendicular. That would mean at 90 degrees to the direction of travel, and I don't think everybody does that. I'm pretty sure I don't, but I don't have CATS data to confirm it.

    I used perpendicular cause I remembered seeing it in a definition of skid in a older bowling book or magazine (I'm looking now to see if I can find it). I believe it is a off shoot from this definition-

    "Axis of rotation. Imaginary line, perpendicular to the track, along which a bowling ball rotates around during it’s initial revolution after the bowlers release."

    But I guess you could say at a angle different than the direction of travel.

    Or heres another definition for you from Ebonite and several other bowling glossarys.

    Skid: The portion of the bowling ball's path in which the velocity of the contact point on the ball is greater than zero, and the ball is not rolling, but is instead sliding down the lane.

    whoops heres another one-
    Skid: where the translational velocity is greater than the rotational velocity.

    Your explanation made perfect sense -- thanks! I'm learning when to make equipment changes. I know that when the ball hits the pocket and just thuds, or I start leaving a lot of 7s and 10s and no lane adjustments help that it's time for a change.

    What type of balls have more skid? Polished and pearls?

    yes, Solids tend to get into a sooner roll.. The polish allows the balls to get further before starting to make the turn on the backends

    Simple enough and accurate.

    The only other minor point is that the ball slows down when it encounters friction. It slows down more when it encounters dry boards than when in conditioner.
