Frequency of a simple pendulum and it's mass

Click For Summary

Homework Help Overview

The discussion revolves around the relationships between the frequency of a simple pendulum and its mass, amplitude, and length. Participants are exploring the factors that influence the pendulum's behavior.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • The original poster questions whether only amplitude affects the pendulum, while others suggest considering the effects of length and mass. Some participants propose experimental approaches to investigate these relationships.

Discussion Status

Participants are actively engaging with the question, with some providing insights into the effects of length and mass on the pendulum's frequency. There is a mix of opinions regarding which factors are significant, and no explicit consensus has been reached.

Contextual Notes

There is an emphasis on exploring assumptions about the effects of mass and length, as well as considerations regarding air resistance, which may not be commonly accounted for in basic discussions of pendulum motion.

hi, i have a question
"What are the relationships between the frequency of a simple pendulum and it's mass, amplitude abd length?"
im pretty sure only the amplitude affects the pendulum while the mass and length don't right?
 
Physics news on Phys.org
Look up (or derive) the formula for the period of a simple pendulum.
 
Im pretty sure only the amplitude affects the pendulum while the mass and length don't right?

Why don't you try it? Tie a ball to a piece of string and have a look.
 
The length does since the arc becomes greater for a same angle. The mass doesn't since for gravity mass doesn't affect the acceleration. Also why not consider the exposed area? That does affect the period since it is related to air resistance.
