If you try to explain acceleration to students, you'll see how unintuitive this concept can be. Most students, even after a course on classical mechanics, can't predict what will happen when you swing a ball around on a string and the string suddenly breaks.

And if you show them a big car pushing a little car through some mud and ask them to compare the force exerted by the big car on the little one to the force exerted by the little car on the big one, they'll usually get it wrong.

Classical mechanics is profoundly counterintuitive at first, which is why it required geniuses like Galileo, Newton and Leibniz to invent it and overthrow the more intuitive Aristotelian picture of physics.
