why with water on the friction coeffiction is bigger?
on the corridor floor the static friction is 2.2N, the dynamic friction is 1.4N
when the corridor floor with water on, the friction is increased, the static friction is 3.8N, the dynamic friction is 3.6N
why with water on, the friction coeffiction is bigger?
and, why with water on the difference between static friction and dynamic friction is decreased?
water can't be a lubricator, but oil can. that is because the surface tension and the molecular structure on them. but what is their difference, and why it can cause the difference on the friction coefficient?
thank u
