Study Notes

Friction

Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other.
Kinetic friction opposes the relative lateral motion of two solid surfaces in contact.
When kinetic energy is converted to thermal energy due to friction, it leads to heat generation.
Calculating friction from first principles is difficult because of the complexities of the interactions between the surfaces in contact.
Friction can be subdivided into two types: static friction and kinetic friction.
