NO,friction depends on area of surface.That is why there are 3 types of friction. 1. Static friction 2. Sliding friction 3. Rolling friction They vary from area of contact. Example You drag a wooden block it will stop after some time and if you drag a same weight of wooden ball it will go further.

hydrometer is used to measure density

Thankyou so much sir. For teaching us.
Measure in density hydrometer is
frictoin doesn't depend up on area of surface contact. it depend on normal force and nature of surface.
Friction is independent to contact between two surfaces
No, it is depend on area of surface ex if you use a nife it's easy to travel but if you use an high surface thing it will stops too earlier than nife
NO,friction depends on area of surface.That is why there are 3 types of friction.
1. Static friction
2. Sliding friction
3. Rolling friction
They vary from area of contact. Example
You drag a wooden block it will stop after some time and if you drag a same weight of wooden ball it will go further.

1st it doesn't always stop
Maybe if there is less friction motion will increse

Sir the ans for measuring density is called hydrometer
density is measured through - hydrometer

Sir your ncert 2 question is incorrect that is NATURE
Why rolling friction less than sliding friction?
Sliding pe Jada force lagta hai
Because of area of contact
Density is measured by hydrometers
