Figure 1: Single-molecule experiments reveal frictional interactions between a pair of sliding F-actin filaments. These experiments reveal several notable features of sliding friction between a pair ...

Frictional forces play a role in many activities – riding a bike, going bowling, and even lighting a match. When two surfaces rub together they create friction, which works to slow movement down. In ...

Unbalanced forces are generally due to a forward force (or thrust) and a frictional force working against each other. Friction is a force that opposes motion. It is present whenever two surfaces rub ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...
