Newton`s Laws
... c. any forces acting on the object are paired, with one force equal in magnitude, but opposite in direction to the other. d. any forces acting on the object are paired, with one perpendicular to the other. e. there is only one force acting on the object, and that force is a frictional force. ANS: a ...

... You have used the model F ≤ μR to solve a range of problems involving friction. What factors determine whether you can use F = μR? You have seen that friction can be the force causing a body to move, or it can be opposing motion. Can you think of any other situations in which friction is either caus ...
