In this video, we break down the concept of the coefficient of friction in AP Physics 1, explaining how static and kinetic friction work and how they affect motion. Clear examples and reasoning help ...

1.1 What is friction? Take this everyday example: when a coffee mug rests on a flat table, the kinetic frictional force is zero. There is no force trying to move the mug across the table, so there is ...

Friction is a force that resists the motion of one object against another. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Scientists began ...

Science presenter Jon Chase explains friction. He describes how friction opposes or prevents motion, and demonstrates the force in action with an experiment involving two interleaved books.
