Cats are excellent teachers of physics. They demonstrate potential as well as kinetic energy. They exemplify Galileo’s two Laws of Motion and Newton’s third law as well. They even illustrate the workings of Intermolecular Forces.
Here is Kedi demonstrating Galileo’s First Law of Motion – A Kedi at Rest Remains at Rest Until an External Force acts Upon Her.
She is also demonstrating the workings of the electrons orbiting around her atomic nuclei and of the Intermolecular Forces that keep her atoms from merging with or falling through the atoms of the couch’s pillow. She’s such a good teacher.
