Explain using laws of physics why pizza chefs use pizza cutters as opposed to equally sharp knives.?

Question

Your answer should include not simply words, but also diagrams and quantitative analysis.

Answer 1

* You gotta be sh**in' me. 2 points

Answer 2

One, it concentrates the downward force of the knife blade onto a small area increasing the cutting ability.

Two, the pizza cutter exerts little perpendicular force so the pizza is not likely to slide.

Note: You could get a large two handled rocker knife to do the same thing, but because it would have to be longer than an extra large pizza, it would be cumbersome to use.

Answer 3

say what ill put it in words but not fregin diagrams n ****
