which surfaces have less friction than rough ones ans for a crossword 5 letters starts with s also a bit of oil reduces this 7 letters 3rd one i
friction is seven letters.
shiny, or oiled surfaces might work.
Thanks bobpursley, both answers fit!
Surfaces that have less friction than rough ones are typically smooth surfaces. When two surfaces are in contact, friction occurs due to the resistance between the two surfaces. Rough surfaces create more friction because irregularities and imperfections make it harder for the surfaces to slide against each other.
In terms of the crossword clues you provided:
1. A word that is five letters long and starts with 's': Given the limited information, there are several possibilities. One word that fits the description is "slick."
2. A bit of oil reduces this and is seven letters long with the third letter 'i': The word you are looking for is "friction." An additional clue for this word is that it refers to the resistance that occurs when two surfaces rub against each other.
I hope this helps! Let me know if you have any further questions.
