Static friction opposes gravity, which acts to pull a wood block down an inclined plane. What is the total value of the gravitational force (Fg) and the force due to friction (Ff) in Newton’s if the wood block is sitting on a flat surface? (A) 0 N (B) 9.8 N (C) 4.9 N (D) 2.8 N
Homework Answers
(A) 0 N
As the block is at rest net force acting on the block must be zero.
component of gravity acts parallel to the surface towards down but static friction acts parallel to the surface towards up.

A block is resting on an inclined plane as shown in the figure below. Static friction between the block and the plane prevents the block from sliding. (Please write legibly. Typing answers is highly suggested.) Draw a free-body diagram for the block. Label all forces acting on it, making sure the relative size of each force is approximately correct. Apply Newton's 2^nd law by writing two equations: one for the forces that lie parallel to plane, and the other for...
