Reversible pendulum
Principle
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
