I'm stumped on how to go about answering this question. It is from a chapter in my Physical Science book dealing with Newton's Laws of Motion...
Why is a massive cleaver more effective for chopping vegetables than an equally sharp knife?

all of your answers so far are incorrect because the more masseous cleaver requires more force to move as well. the reason the cleaver is more effective is because it's inertia will cause it to slow less on initial impact with the vegatable material thereby allowing better penetration of the matter you're cutting. it only has to do with mass by tangent.

That is essentially correct. The heavier mass of the cleaver has more momentum. Momentum = mass x velocity. So a heavy cleaver will be better at chopping than a light knife unless you chop with the knife at a much higher velocity than the cleaver.

Because the cleaver is heavier--therefore it exerts a larger force on the fibers of the vegetables, and these have to be broken for the vegetables to be cut.

Because it has more mass. Force = mass x acceleration. More mass equals more force.

More power in the handle?
