A compact, low g range accelerometer comprising a support (22), a proof mass (20), flexures (24, 26) for mounting the proof mass to the support, and a force sensing element (40). The proof mass has a single rotational degree of freedom about a hinge axis (H) perpendicular to the accelerometer's sensitive axis (S). The force sensing element is positioned along a line that is normal to the hinge axis and that lies in a plane that is normal to the hinge axis and that passes through the center of gravity (46) of the proof mass. The perpendicular distance between the hinge axis and the force sensing element is less than the distance between the hinge axis and the center of the proof mass. The force sensing element may be parallel to the pendulous axis, to produce an extremely compact accelerometer, or may be oriented at an acute angle with respect to the pendulous axis, such that the line along which the force sensing element is positioned passes through the center of percussion of the proof mass.
