Two come to mind, the ball slows down as it goes further down the alley.
as the ball spins, the friction generated causes the ball to curve.

Friction
Because it's friction that rubs the graphite off the pencil on to the paper to make the words you write.
Everywhere, for example sitting on your chair, walking, using a mode of transport.
The word bowling is a noun, a verbal noun called a gerund (using the -ing form of a verb as a noun). Example sentence:Bowling is my father's favorite sport.
No. Whenever two objects touch, even in the slightest degree, there will be friction. We minimize friction using lubricants such as oil or graphite, or by reducing the amount of drag that is happening; for example, using a wheel instead of a skid.
If you are speaking of the ball friction on the lane, it can be reduced by the lane oil used by the center lane maintenance crew or reduced by using ball that has been sanded with fine sand paper grit and polished.
I never heard of friction reducing friction. You can reduce friction by using lubricants, as well as using wheels (as in ball bearings).
One example would be a scientist using tennis balls to show the position of the planets and the sun.
A lubricant such as oil, grease, graphite powder or PTFE can reduce the friction between two surfaces. Or using metal balls to space them and reduce the contact surface area as used in ball bearings.
There are a few ways to reduce friction. For example one can apply water or oil to the surfaces that are rubbing together.
There are two types of friction : static friction and kinetic friction. Static friction occurs when two objects are touching but are not moving relative to each other. For example, static friction can prevent a box from sliding down a slope. The static friction between this box and the slope (and between any objects) can be calculated using the equation : Fs = µsN where µs is the coefficient of static friction and N is the normal force. Kinetic friction occurs when two objects are touching and moving relative to each other. For example, the kinetic friction slows down a box sliding down a slope. Also, when two surfaces rub together, there is kinetic friction. The kinetic friction can be calculated using the equation: Fk= µkN where µk is the coefficient of kinetic friction and N is the normal force.
