Variable g pendulum with Cobra SMARTsense

Principle

Earth's gravitational acceleration g is determined for different lengths of the pendulum by means of the oscillating period. If the oscillating plane of the pendulum is not parallel to the gravitational field of the earth, only one component of the gravitational force acts on the pendulum movement.

Tasks

1. Determination of the oscillation period of a thread pendulum as a function of the pendulum length.
2. Determination of g.
3. Determination of the gravitational acceleration as a function of the inclination of the pendulum force.
