Question

How does friction help us to hold things safely in our hands

Open in App
Solution

Dear Student ,

We are able to pick up book and hold it in our hands due to the friction between the book and the hands.We can hold a glass tumbler in our hands because of friction. If the outer surface of a glass tumbler is oily all greasy then it becomes more difficult to hold it.This is because the presence of a film of oil on the outer surface of glass tumbler reduces the friction between glass tumbler and our hands.Due to less friction the oily glass tumbler tends to slip from our hand and it becomes more difficult to hold. It is easier to hold a kulhar in our hands than a glass tumbler.This is because due to the rough surface of the kulhar the friction between Kulhar and our hand is much more which makes it easier to hold it. Due to the smooth surface of glass tumbler the friction between glass tumbler and hand is much less which makes it comparatively difficult to hold it.
