Troll physics explained

Rage comics are one of my guilty pleasures. Combine them with my love for science, and you can’t go wrong. A physics professor was asked to explain the (lack of) science behind some of the funnier “Troll physics” comics. Here’s one of my favorites:

“DM: Jumping off the ground – or even a chair on the ground – is nothing like jumping off a chair while you and the chair are in freefall. Because the chair isn’t connected to anything, you’ll be pushing the chair DOWN as much as pushing yourself up (via Newton’s third law). And since you have much more mass than the chair, the force you and the chair exert on one another will speed up the chair’s descent much more than it slows your own.”

Is it bad that I think I would have learned more from my physics class if it would have incorporated internet memes?
