AP Physics C - Unit 2.3 - Horizontally-Moving Systems

You’d think when objects move horizontally, the physics problem behind it would be straightforward - but sometimes it’s not so simple! This video covers three common setups and examples for how forces can affect the motion of an object moving horizontally along a surface, both with and without friction.
