Which notations are commonly used on force diagrams to show forces acting on an object? check all that apply. fp, fz,
fn,
ff,
fd,
fg

Force diagrams are used in physics in order to help solve problems involving mechanics. There are a number of forces that can be labelled upon a force diagram and this includes FN (Normal force), Ff (Friction force) and Fg (Gravitational force). When a system is in equilibrium, forces within a force diagrams should add to zero.
