Q. Why is sharp knife more effective than a blunt knife?
Pressure is inversely proportional to area. Sharp knife has a small area of contact than the blunt knife. Thus, a force will exert more pressure while using a sharp knife than while using a blunt knife.
Q. Why is a sharp knife more effective?
A sharp knife has a smaller area that comes in contact with the object and hence more pressure can be applied on the object.

Q. Are sharp knives more effective than dull knives?
The cutting edge of a knife that has been sharpened has a smaller surface area than a dull knife. Since pressure is force per unit area, a sharp knife will exert a higher pressure with the same amount of force and cut through material more effectively.
Q. Why is a sharp knife more effective in cutting a fruit than a blunt knife Class 8?
Explanation: A sharp knife cuts fruits and vegetables more efficiently than a blunt knife because, the surface area of the knife is lesser than the blunt knife. ➡️When the surface area is lesser, the sharp knife can easily cut through the fruit or vegetable making it easy to cut.
Q. Why is sharp edge blade more effective in cutting than blunt blade?
In a blunt blade, the force applied on blade spreads over a large area as compared to sharp blade. Consequently, the pressure of the force applied is much more in sharp blade, and hence it is more effective in cutting an object.
Q. Why does a knife become blunt with use?
As we know, The force of friction acts between all moving bodies, which are in contact with one another.So here Knife is in contact with another bodies such as vegetables.So when we cut vegetables with knife then the surface of knife and Surface of vegetables wear off on each other.So after long use surface of knife …
Q. Why Sharp knives are safer?
The whole reason a sharper knife is safer comes from the fact that sharper knives promote better cutting techniques. A sharp knife can cut using the edge of the knife with a safer slicing, rather than stabbing, motion. Another unsafe practice is using too much force in your cut.
Q. Why would a chef use a sharp knife instead of a dull knife Brainly?
Explanation: A sharp knife cuts objects better because of its very thin edge, a large pressure can be created on the object when the force falls over a sharp small area of our hand. The dull knife exerts a small pressure on the surface due to the large area of contact.
Q. Why do we prefer a sharp edged knife for cutting?
A sharp knife cut objects better because due to its very thin edge, the force of our hand falls over a very small area of the object producing a large pressure and this large pressure cuts the object easily. While a blunt knife has a thicker edge. This lesser pressure cuts the object with difficulty.
Q. Why do sharp knives cut vegetables easily?
A sharp knife has a relatively lesser area of contact with the vegetable, as a result, the force can effectively be concentrated on the area without getting wasted. Therefore, we always use a sharp knife in a knife for efficiency.
Q. Why does a sharper side of a knife cut more easily than blunt side?
Answer Expert Verified The lesser the area of contact of a given body, the more is the pressure exerted by it. The blunt knife has more area hence the pressure exerted is less while the sharp knife has less area hence the pressure exerted is more, therefore, it is easier to cut an apple with a sharp knife.
Q. Why is the cutting edge of the knife made very thin?
As Area decreases, Pressure Increases. P is inversely proportional to Area. Thats why cutting edge of knife is made with very less Area.
Q. Why is a sharp knife more effective in cutting objects?
Because sharp edge will shear the surface of the object better than a blunt edge. The sharp edge has smaller surface area and imparts greater pressure for the same applied force. It’s practical in life as well. Try it at your home, take a sharp knife from the kitchen and try to cut some vegetable with it and observe the pressure that you applied.
Q. Which is safer, a sharp knife or a blunt knife?
A sharp knife used properly is safer than a blunt knife used in the same way.
Q. Which is better a sharp edge or a blunt edge?
Because sharp edge will shear the surface of the object better than a blunt edge. The sharp edge has smaller surface area and imparts greater pressure for the same applied force. It’s practical in life as well.
Q. What kind of edge does a knife have?
Knives have a very fine edge, but at a microscopic level they still have very very fine teeth on a very thin edge. As a knife gets used a combination of things happen. Imagine that a knife is a wedge shape w…
