A ball rolls down along an incline without slipping. A block slides down from the same incline without friction. Assuming the two objects start from the same position, which of the following statement is correct?

Solutions

Expert Solution

from the above two arguments one which is correct and acceptable is:

i) A ball rolls down along an incline without slipping.

Practically any surface without any friction ,is not real we cannot have a surface which has no friction or its friction less.

when a ball rolls down an inclined plane ( with some descent angle) it is possible that when it rolls down , it happens without slipping if the surface has high friction coefficient such that no slipping occurs , which is evident by the fact that when we descend down an inclined hill we can perform our task without any slipping by wearing some short of tracking shoes, so yes it is possible and practical.

but if we say that the block slides down the incline plane without any friction , it practically not possible , because every surface posses some friction and if it said that it slides down the incline without friction is not true in fact it is just a theory.
