Can a force of 700 newtons cause much damage?

Oh, dude, 700 newtons? That's like asking if a squirrel can take down a skyscraper. I mean, sure, it could cause some damage if you throw it at someone's face, but in the grand scheme of things, 700 newtons isn't exactly gonna start a war or anything. So, like, it depends on what you mean by "much damage."
