Homework Help Overview

The discussion revolves around the effect of a melting ice bob on the time period of a pendulum. Participants explore how changes in the bob's mass might influence the pendulum's oscillation characteristics.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants question the relationship between the mass of the bob and the time period, referencing the formula for the time period of a pendulum. There is a focus on whether the melting ice, which reduces weight, has any impact on the time period despite the formula indicating mass independence.

Discussion Status

The discussion is ongoing, with participants providing hints and questioning each other's reasoning. There is no explicit consensus, but some guidance has been offered regarding the independence of the time period from mass.

Contextual Notes

Participants are navigating assumptions about the effects of mass and gravity on the pendulum's time period, with specific reference to the properties of the melting ice bob.

Hi,:smile:
Do you know the formula to calculate Time period of a pendulum ?
 
Hint:
Melting of Ice reduces its weight.
 
formula of time period is T=2*pi root over l/g
so how does reduction of weight helps out?...i mean time period is not dependent on mass and gravity remains constant at a particular place (weight =mg)...?
 
That is the trick.You almost got it.

Not sure how that's a hint.

The period of the pendulum is independent of the bob mass. Ah, Galileo's wonderful discoveries.

Seems you did not read my next post :p

so if g remains constant...then there is no effect on time period?
 
nopes.
