# What is responsible for cutting an apple: pressure or force?

To cut an apple, do I need more pressure or more force? When we want to destroy the intermolecular bonds, don't we need more force ?

You can have a lot of force, but that does not necessarily mean you can cut the apple. Remember that $$P=F/A$$ So if you have a sharp knife you only need a small force because the pressure will be enough to slice through the apple.
