By means of a reversible pendulum, terrestrial gravitational acceleration g may be determined from the period of oscillation of a physical pendulum, knowing neither the mass nor the moment of inertia of the latter.
Benefits
Quick and easy set-up
Determine the gravitational constant g immediately without knowledge of mass or moment of inertia
Automatically measure the oscillation period using the light barrier
Tasks
Measurement of the period for different axes of rotation.
Determination of terrestrial gravitational acceleration g.
