Abstract

An absolute gravimeter which has been designed and constructed consists of a timing circuit which measures the time a body takes to fall between two points separated by a known distance. The time of fall and the known distance are used to calculate the acceleration of gravity at the point of experimentation. Test measurements around some points where gravity acceleration is known shows that the gravimeter gives reliable results.

KEY WORDS: Absolute gravimeter, timing circuit, acceleration of gravity, reliable results.
