Experimentally measure gravitational force

Click For Summary
SUMMARY

The discussion focuses on the experimental measurement of gravitational force, specifically referencing the Cavendish experiment conducted in 1797. It highlights resources for conducting modern versions of the Cavendish experiment, including undergraduate laboratory setups and commercially available apparatus from companies like Pasco Scientific. Additionally, it mentions the availability of "homemade" versions of the experiment through platforms like YouTube. The Forward Mass Detector is also introduced as a relevant topic for further exploration.

PREREQUISITES
  • Understanding of gravitational force measurement techniques
  • Familiarity with the Cavendish experiment methodology
  • Knowledge of laboratory equipment used in physics experiments
  • Basic principles of gravitational physics
NEXT STEPS
  • Research undergraduate laboratory versions of the Cavendish experiment
  • Explore apparatus options from Pasco Scientific for gravitational experiments
  • Watch YouTube videos on "homemade" Cavendish experiments
  • Investigate the Forward Mass Detector and its applications in measuring gravitational forces
USEFUL FOR

Students in physics, educators conducting experiments on gravitational forces, and hobbyists interested in experimental physics will benefit from this discussion.

Can we experimentally measure the very weak gravitational force between two objects just like we can detect magnetic field lines by a deflecting compass.
