Question

Why sharp knife can cut better than blunt knife?

Answer 1

That is because pressure is inversely proportional to area, lesser is tye contact area more is the pressure. Sharp knife have less area as compared to blunt one.therefore sharp knife can cut better.

Answer 2

 Hello buddy..

- A sharp knife has a very thin edge to its blade. A sharp knife cutsobjects better because due to its very thin edge, the force of our hand falls over very small area of the object producing a large pressure. And this large pressure cuts the object easily. On the other hand, a blunt knife has a thicker edge.

Hope it helps you buddy
