I never realized before how physics is everywhere until I started watching a movie. Most of the time cartoons dont seem to follow the rules of physics and it becomes obvious. While watching "Scooby Doo Meets the Boo Brothers", I realized Scooby and Shaggy dont really follow the physics when running from the ghosts or people. They kinda just decide to do their own thing like usual.
So, Scooby and Shaggy jump up in the air, start running in air then zip off into the distance running away. But what comes up must come down. They should just fall back down due to gravity and no force pushing them forward. While the two are suspended in air the force of gravity (mg) acts upon them dragging them down. In order for them to rush forwards like they did they would need a force coming from the side to push them forward to where they were going. Plus they have no initial velocity so they're kinda stuck where they would be. Good thing they dont follow the world of physics.
