Why does it rip when you tug sharply on toilet paper, rather than just unravelling as it would if you tugged with less force, but quicker?

That’s not physically possible. Force is mass × acceleration. A sheet of toilet paper always weighs the same, ∴ if you pull it quicker it will automatically be with more force. Anything else is physically impossible.

When you pull quicker, you’re using more force, but over a shorter amount of time. With more force, the serrated part of the toilet paper becomes the weakest link and breaks.
