Which of the following statement is not true ?A.Friction can be reduce

1.	Which of the following statement is not true ?A.Friction can be reduced by converting sliding friction into rolling frictionB. Friction in air and water can be reduced by streamlining the shape of the objects.C.A polished surface will have less frictionD.Friction can be reduced to zero
Answer» CORRECT option is D Friction can be reduced to zero We can REDUCE the friction between two surface by polishing the surface, by converting the shape of body like rolling friction is less than SLIDING friction so we can use tyres in PLACE of sliding the object. Friction can be minimized but cannot reduced to zero. Option D is not TRUE.

Answer»

Friction can be reduced to zero

We can REDUCE the friction between two surface by polishing the surface, by converting the shape of body like rolling friction is less than SLIDING friction so we can use tyres in PLACE of sliding the object.

Friction can be minimized but cannot reduced to zero.

Option D is not TRUE.
