Question

The magnitude of force of friction can be known using a​

Answer 1

1. g cosθ. The component of the net force down the slope is F = mg sinθ - μkmg cosθ. It is the vector sum of the frictional force and the tangential component of gravity.
2. Friction depends on both of the materials involved. The magnitude of static friction fs between systems stationary relative to one another is given by fs≤μsN f s ≤ μ s N , where μs is the coefficient of static friction, which depends on both of the materials.
