There's Physics in Cartoons

Recently, I have been thinking about many things. Let's just say, I've been daydreaming a lot lately. Most probably because I find it much hard for me to concentrate in class and I would fall asleep once in awhile. And, on one particular day, I have been doing my routine(daydreaming) during Physics lesson, I just found out the reason why Tom never caught Jerry, Sylvester never caught Tweety, Elmer never caught Bugs Bunny, Road runner and coyote, so on..... It is all because of physics, inertia.... those chasers are much larger than what they are chasing. Which means they have greater mass than whatever they are chasing and that makes them to bump into a wall or some other obstacles more often while making turns.... It took me long enough to realise cartoon does applies Physics, but not all though, at least most of them do....
