SUMMARY

The discussion centers on calculating the time it takes for a pencil to fall flat after being slightly pushed off balance. Participants emphasize that this is not a straightforward problem due to the pencil's Moment of Inertia, which complicates the dynamics of the fall. Newton's laws provide a foundational approach to estimate the time, but the unique properties of the pencil must be considered for accurate results. A reference link is provided for further exploration of the topic.

PREREQUISITES
  • Understanding of Newton's laws of motion
  • Familiarity with the concept of Moment of Inertia
  • Basic knowledge of rotational dynamics
  • Ability to interpret physics-related articles
NEXT STEPS
  • Research the principles of rotational motion and Moment of Inertia
  • Explore the application of Newton's laws in real-world scenarios
  • Study the dynamics of tipping objects and their fall times
  • Review physics simulations that model falling objects
USEFUL FOR

Physics enthusiasts, students studying mechanics, and anyone interested in the dynamics of falling objects will benefit from this discussion.

i have a pencil standing upright. How do i calculate the time it will take pencil to fall flat on ground if given a slight push to off balance. This is not homework. just thinking about it.

It's not that simple.
You could use Newton's idea to get a rough answer.
Things which have mass attract other things which have mass,

A pencil has a significant Moment of Inertia so it is more than a simple falling mass calculation.
