Troll Physics – an amusing teaching tool?
Olwen sent me a link to a Youtube video about “Troll Physics” – videos that are meant to “troll” or annoy anyone who knows some physics. How To Travel The World Gratis
They’re actually quite funny, but the really interesting part is that some of them can be used to teach physics. For example, take the magnet car. This could be used to help teach something about Newton’s Laws: the magnet and car exert the same force on each other, but the magnet has considerably less mass than the car, so the magnet experiences a larger acceleration than the car and is stuck to the car.
Elsewhere, I found an article where somebody showed Troll Physics to a physics professor. And yes, he apparently gets the joke.
