    Melting Pendulum
AI Thread Summary
The discussion centers on the effect of a melting ice bob on the time period of a pendulum. It highlights that the time period, calculated using the formula T=2π√(l/g), is independent of the bob's mass. Participants clarify that while the melting ice reduces the bob's weight, it does not affect the time period since gravity remains constant. The conversation emphasizes the understanding of pendulum mechanics and the implications of mass on oscillation. Ultimately, the melting of the ice bob does not influence the pendulum's time period.

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 dependant 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.
