Krakauer's discovery that his father had been involved in a sexual assault case, which his father handled poorly, intensified the friction in their relationship. This incident challenged Krakauer's perception of his father and their relationship, leading to increased tension between them.
They're both forms of static friction.
The more uneven the surface, the more friction there is.
Because the size is a kintec force on it
The relationship between friction and the efficiency of a machine is when friction increases, efficiency decreases, and vice versa. That is why you can never have 100% efficiency, because there is always at least a little friction. They are inversely proportional, meaning, higher friction equals less efficiency.
An ideal machine has no friction. -Nn
Generally, the higher the contact force, the higher the friction.
FRICTION !
Yes. Without sliding friction or rolling friction, we would not be able to walk. It is the relationship between gravity, friction, and mass.
they are directly proportional, the greater the mass, the greater the sliding friction
Friction decreases the speed of something rubbing against something else.
Throw in variances in road surfaces with friction and tire surface area and the relationship is very unusual... you might call it a 'manage-et-trois'.
There is no simple relationship. However, the general tendency is that rougher surfaces have a greater coefficient of friction.
