Question

Why sharp knife cuts better than a blunt knife

Answer 1

Explanation:

Sharp nice cut better than blunt knife because of its small area.

As pressure is inversely proportional to area so a sharp knife applies a large pressure on the objects which needs to be cut. ( since smaller area-- larger pressure)

Answer 2

Answer:

A sharp knife cuts better than a blunt knife because sharp knife has very thin edge and the force of our hand falls over a very small area of the object producing a large pressure.
