Quick Reference

An instrument for measuring the gravitational acceleration. Most field instruments are relative instruments, i.e. they determine the difference in gravitational acceleration between two or more points. Most operate by determining the change in extension of a spring loaded with a constant mass. Laboratory instruments can be absolute and are based on dropping masses, vibrating strings, or oscillating pendulum systems.
