Which force produces acceleration in falling bodies?

The graph describes the motion of an object. the object moves with from a to b. it from b to c. it moves with from c to d.

Ablock having mass m slides down an inclined plane. the force of friction between the block and the inclined plane is f, the block's weight is m g, and the normal force is n. (a) draw a free – body force diagram showing the forces acting on the block. (b) write down all relevant newton’s equations for a given situation.
