SUMMARY

The discussion focuses on calculating the acceleration due to gravity, 'g', using simple methods without advanced equipment. The pendulum method is highlighted as a basic yet effective approach. Additionally, dropping a ball from a known height and measuring the fall time is presented as an alternative method, utilizing the equation s = 1/2 gt² to derive 'g'. Minimizing air resistance is emphasized for accurate results.

PREREQUISITES
  • Understanding of basic physics concepts, particularly motion and gravity
  • Familiarity with the pendulum method for measuring time
  • Knowledge of elementary equations of motion
  • Ability to measure height accurately
NEXT STEPS
  • Research the mathematical derivation of the pendulum method for calculating 'g'
  • Learn about the effects of air resistance on free fall experiments
  • Explore advanced techniques for measuring time, such as using a stopwatch or smartphone apps
  • Investigate other methods for measuring 'g', such as using a spring scale or oscillation of a mass
USEFUL FOR

Students in physics, educators teaching basic mechanics, and hobbyists interested in conducting simple experiments to measure gravitational acceleration.

The Attempt at a Solution


I only know of the pendulum method.
Can someone please show me of other methods to calculate g without the use of fancy equipment such as a picoscope.

The pendulum method is generally the most elementary method that gives a reasonably accurate result quite easily.

Another method is to drop a ball from a known height, h meters, and to measure the time it takes to fall to the ground. By elementary equations of motion, we find

[tex]s= 1/2 gt^2[/tex] and hence we can easily determine a value of g from this.

Be sure to minimize air resistance for a decent result.
 
Thanks
