Pls explain this:
To hold a glass of water, friction is necessary. Due to friction present between our fingers and the outer surface of the glass, we are able to grip the glass of water. If there was no friction present, it would not be possible to hold it.
Yes the above statement is true because if there is no friction the glass will slip from our hands .
in terms of physics there is one force acting in the vertical direction which is mg (gravitational force of attraction)
hence to balance this force we need a force in opposite direction so that it balances it or cancel it and the glass remains in equilibrium position in our hands. hence this opposite balancing force comes from friction between glass and our fingers .
