measurement of gravity

Gravimetry

most commonly used unit

Gal

1 gal = ___ m/s²

0.01

determines the gravity g from the fundamental acceleration quantities length and time.

Absolute gravity measurement

based on the equation of motion of a freely falling body.

the free fall method

no longer applied today but governed gravimetry for about 300 years.

the pendulum method

In reality a string will not be without mass and the mass will not be a point mass.

Physical Pendulum

fictitious pendulum described by a point mass m on a massless string of length l, that can swing without friction around its suspension point or pivot.

Mathematical Pendulum

Corrections applied for absolute gravity measurements

Tides, Pole tide, Air pressure, Gravity gradient, Changes in groundwater level

Foraccuracies in the 1-10 μGal, a ______ is used.

laser interferometry

gravity is determined from measuring the time it takes a proof mass to fall a certain distance z.
