What type of friction is used in the water parks and car wheels? how are you able to slide so easily in water parks?

This is all about kinetic friction....
We are able to slide on water slides because there is smooth surface which decrease the friction ...

ericksonrjoseppcsukt: Please review your answers before submitting them to people who ask for help, the questioner may not know that there kinetic friction is no different than regular friction, and if the question refers to water parks, it is obvious that the "easily" is relative to other places such as slides in regular parks.

Iamkeetarp: My ans was exactly relating to the question...

ericksonrjoseppcsukt: 1. you do not answer "what type of friction is used" with friction.
2. Water slides and regular slide have smooth surfaces alike. The difference has to do with the presence of water, and not the smooth surface of the slide.
3. Smooth surfaces do not "decrease the friction," but rather it has less friction.

Iamkeetarp: frition depends on the surface ..... that is why i wrote it...

ericksonrjoseppcsukt: Arupr9995 did not ask if friction depends on the surface, rather what kind of friction. Moreover, the reason the questions specifically states "water parks" is because the answer has to do with the interaction of both surfaces and water.

Iamkeetarp: okkkkkkkkk

There are 4 types of friction: static, sliding, rolling and fluid friction. The friction used in water parks and car wheels is sliding friction, as it involves two surfaces to slide against each other.

Friction is caused by micro irregularities in both surfaces that get caught up with each other. In water parks, water insulates (covers) these small gaps, reducing friction and making it easier to slide
