The title says it all: this blog features physics videos found everywhere on the web: animations, demonstrations, lectures, documentaries.
Please go here if you want to suggest other nice physics videos, and here if I mistakingly infringed your copyrights. If you understand French, you'll find a huge selection of physics videos in French in my other blog Vidéos de Physique.

Block and spring system

Hooke's Law: force exerted by a spring

Hooke's law: the magnitude of the force exerted by a spring is directly proportional to the distance the spring has moved from equilibrium.

Conservation of energy

The block slides on a horizontal frictionless surface. K is kinetic energy. U is elastic potential energy and E is total mechanical energy. While potential energy is converted to kinetic energy (and vice versa), total mechanical energy remains constant.
