why is it easier to cut an apple with a sharp knife rather than a blunt one?

Dear Student! Aneeta

If the edge of knife is sharp, apple can be cut easily  without much effort. This is because, area of the sharp edge is highly minimized which causes a very high pressure on the apple. On the other hand in case of blunt knife, even a good effort may go futile as the pressure applied by its edge may not be sufficient to cut the apple.

A similar explanation can be given in case of sharp or blunt nail, when you hammer it into the wall.

Hope it is clear to you!

 When we apply force on a blunt knife to cut an apple, the area on which the force is applied is greater and so the effect is less.The opposite takes place when we apply force on a sharp knife. Thus less force has to be applied on a sharp knife and cutting an apple becomes easier.

Coz a sharp's knife's area is less so the pressure increases which helps to cut the knife where as in a blunt knife the contact area is more so pressure is less. Hence it is easier to cut an apple with a sharp knife......

Hope it helped Aneeta.....
