Use the spaces below to take notes on the key concepts presented in this study.
Main idea: Friction is the force that opposes motion when two surfaces rub together.
The force that opposes motion when two materials touch each other. causes object to accelerate downward
The force between two objects at rest that opposes their sliding relative to each other.
The frictional force encountered by an object in motion.
types of surfaces involved how hard the surfaces are pushed together
Used to calculate how strong the force between two surfaces is. “mu” always between zero and one coefficient of kinetic friction always less than or equal to that of static friction waxed ski on snow rubber on dry concrete ice on ice
glass on glass
Tiny collisions, made between two surfaces sliding against one another, that collectively produce friction.
