A physics joke today :) This one is kinda easy and you can get it if you passed high school physics. I post it here today just because I saw it today on Pinterest and I love cats.
Joke explained: mew is a Greek Letter μ, the coefficient of friction. f=μN, so friction is relevant to NOT gravity BUT normal force, the force pendicular to the surface the object is on. By the way, there are two kinds of frictions: static fs=μsN and kinetics fk= μκN. μκ and μs depend on the roughness of the two surfaces touching each other. μs can not be bigger than μκ (guess why~ or ask me in DM)
If the force is bigger than friction, the object accelerates. If smaller, it either doesn’t start moving or it decelerates.
So the smaller the mew, the faster the cat slides down the roof :) And mew sounds like meow, of course.
