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
(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 at rest on an inclined plane (shown in diagram). Coefficients of friction are μ-02, μ,-0.17. Gravity is 9.8 m/s2 Okg What is the normal force on the box? Let's assume friction were not a factor-the box would slide down the ramp. What is the magnitude of the force that causes the box to24 down the ramp? What is the static friction force on the box? Will the box slide without being pushed down the ramp? What is...

A block slides up an inclined plane while slowing down as it moves. Which of the following statements about the friction force must be true? The friction force is greater than the gravity force. The friction force is greater than the normal force. The friction force is greater than the component of the gravity force parallel to the ramp.

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...
