Subject :NSO    Class : Class 8

Read the given passage and answer the questions 46 and 47.
The force of friction not only tends to stop a moving object, it also tends to stop a stationary object from moving. That is why it is difficult to push a stone to get it to move on a rough surface.

Friction is almost independent of.
(i) velocity of moving body
(ii) Weight of moving body
(iii) Nature of contact surface of moving body
(iv) Shape of moving body

A(i) and (iv)
B(ii) and (iii)
C(ii) only
DNone of these


when velocity is 0 static friction comes into play and when the velocity increases kinetic fraction comes into action and thus the friction decreases

Ans 1:

AADRIKA KUMAR from MOUNT LITERA ZEE SCHOOL, Kanpur
Class : Class 5
But if the shape of the object is streamlined then then the force of friction exerted on it will be less

Ans 2:

BEENA THOMAS from BCRS, Thiruvalla
Class : Class 6
AND when shape of an object is spherical it undergoes rolling friction and when the shape is a flat surface the moving object undergoes sliding friction which is greater than rolling friction

Ans 1:

Nishant Doshi from new era senior secondary school nizampura vadodara, Vadodara
Class : Class 7
The correct option is D because there are 4 heaps of cubes and each have 4 cubes so 4 multiplied by 4 = 16 so 16 + the front cubes , there are 10 cubes in one line at up and 10 at bottom so 10 + 10 = 20 + 16 which equals to 36 . Thus it is the correct answer .
