A gentle tap with a big hammer - how does that work?
Writing something a few days ago, I came across this picture and was reminded that I meant to post it here and ask a question.
In the photo, I'm forcing a Wills Cattle Creep wall into a foam baseboard. By gently tapping it with a big hammer several times, I was able to shove it in to the foam without damaging the plastic part and with plenty of control.
Had I used a smaller hammer, I'd have had to whack it hard to get the same effect, smashing the plastic.
The question: Why is easier to give things a gentle tap with a big hammer than a small one?
Something to do with momentum? I can use the principle, but can't entirely get my head around why it works. That bothers me, which is why I'm asking you.
