Adhesion and Friction
2 surfaces stay in contact without slipping
Holds 2 parts together
FORCE that resists slipping
Increases with adhesion
Need grip for movement (climbing boots, car tires)
Parts move efficiently (friction wheels)
Pulling something heavy (sleigh on snow vs ice)
Parts need to slide (pistons)
