Summary: Friction Friction is a Force that opposes the relative
... Friction is a Force that opposes the relative motion of two surfaces in contact. Its magnitude is determined by two factors: 1. The “roughness” of the surfaces together. This is quantified using the “coefficient of friction”, μ. a. this number is always > 0 b. this number has no units c. this number ...

Big Idea
... Big Idea: All forces arise from the interactions between different objects. Concept: When two surfaces of objects are in contact with each other, the force of friction between them depends on the nature of the materials in contact and the normal force. Competency: Construct a free body diagram indic ...
