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.
I never heard of friction reducing friction. You can reduce friction by using lubricants, as well as using wheels (as in ball bearings).
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.
The tennis balls serve several purposes. They make it easier for the walker to slide across the floor, rather than the friction from the rubber bottoms. They also prevent scuff marks on the floor. The tennis balls on walkers serve a dual purpose. First, they allow the person that is using the walker to
by using a lubricant to decrease the friction.
By using kinetic friction
You can describes the friction
