Here's a more detailed explanation:
* Friction is a force that opposes the motion of one surface sliding over another. It arises from the microscopic interactions between the surfaces in contact.
* Static friction acts when the surfaces are at rest relative to each other. It prevents the surfaces from starting to move.
* Kinetic friction acts when the surfaces are in motion relative to each other. It tries to slow down the motion.
