what is sliding friction
Answers
Explanation:
The term sliding friction refers to the resistance created by two objects sliding against each other. This can also be called kinetic friction. Sliding friction is intended to stop an object from moving
Kinetic friction, also known as dynamic friction or sliding friction, occurs when two objects are moving relative to each other and rub together (like a sled on the ground). The coefficient of kinetic friction is typically denoted as μk, and is usually less than the coefficient of static friction for the same materials.[37][38] However, Richard Feynman comments that "with dry metals it is very hard to show any difference."[39] The friction force between two surfaces after sliding begins is the product of the coefficient of kinetic friction and the normal force: {\displaystyle F_{k}=\mu _{\mathrm {k} }F_{n}\,} F_{k}=\mu _{\mathrm {k} }F_{n}\,.
