Comments on: One type of coffee grinder has a small blade that rotates very rapidly and cuts the coffee beans into powder.? http://youthinside.org/2007/11/17/one-type-of-coffee-grinder-has-a-small-blade-that-rotates-very-rapidly-and-cuts-the-coffee-beans-into-powder/ All About Shopping Sat, 19 May 2012 15:19:56 +0000 http://wordpress.org/?v=2.3.1 By: amit j http://youthinside.org/2007/11/17/one-type-of-coffee-grinder-has-a-small-blade-that-rotates-very-rapidly-and-cuts-the-coffee-beans-into-powder/#comment-873 amit j Wed, 21 Nov 2007 10:10:15 +0000 http://youthinside.org/2007/11/17/one-type-of-coffee-grinder-has-a-small-blade-that-rotates-very-rapidly-and-cuts-the-coffee-beans-into-powder/#comment-873 hello. good intiuition. basically you see the concept of inertia play here. Imagine yourself in the jar : as the blade tende to strike the coffee beans the beans' inertia thes to resist any change in their position and state of motion. but the blow is rather jolting and cannot be described by the everyday notion of pushing or pulling etc. Rather u may better understand it as an IMPULSE which acts on the beans and rupture the molecular bonds and lattices, before the force of strike can travel to the other end of the bean. Thus I and U can enjoy tne finely ground beans....... Thenks to IMPULSE. Goodbye hello. good intiuition. basically you see the concept of inertia play here.

Also they break up as they encounter other bean particles at great speeds. Mathematically inertia has everything to do with that F=ma Force F applied moves an object of mass m with acceleration a. If the force is too small an object will not even budge however if the force is too great an object will break up. The blades move faster than the coffee beans can get out of the way.

F=ma

Force F applied moves an object of mass m with acceleration a. If the force is too small an object will not even budge however if the force is too great an object will break up.
