when 2 surfaces rube or slide together the more smooth the less friction
boundary friction
Friction is present at the motor shaft and also in various parts of the load. The friction torque is equivalent value of various friction torques referred to the motor shaft.
For example the cause of sliding friction of two materials is when the stress between the Materials is not equal to zero
"magnetic" "levitation" A cute way to make trains float - thus reducing rolling friction, but NOT air friction.
The friction that two surfaces excert on each other when they rub against each other is called a friction.
Friction can make object no.
Friction definitely is a force that can make things easier. Stopping a car for example is made easier by friction.
yes, because it has kinetic friction which make it slide.
usually when you rub on to something it creates heat so that makes friction. Ice has no friction because it slips

You would have to overcome sliding friction to make a book move across a desk. Sliding friction is the force that resists the motion of two surfaces sliding against each other.
False. Friction is a force that resists motion, so it can make work more difficult rather than easier. Minimizing friction can help make work easier.
Different substances produce different amounts of friction. But generally, rough surfaces produce the maximum friction.
yes. there is friction to resist every movement we make
friction is rubbing two items together to make friction without is your breaks on the car they would be useless friction causes heat - Brenner Fodt age 12
Friction is important because without friction we would be sliding and slipping everywhere as friction slows down and stops things. Friction occurs when two things touch or make contact.
To increase friction, you can roughen the surfaces in contact or increase the force pressing the surfaces together. To decrease friction, you can make the surfaces smoother or reduce the force pressing the surfaces together.
