Reversible pendulum with Cobra SMARTsense

Article no: P2132267

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

Tasks

  1. Measurement of the period for different axes of rotation.
  2. Determination of terrestrial gravitational acceleration g.

Learning objectives

  • Physical pendulum
  • Moment of inertia
  • Steiner's law
  • Reduced length of pendulum
  • Reversible pendulum
  • Terrestrial gravitational acceleration
