What would be the best conclusion from these data?

The period of a pendulum is linearly related to the mass of the bob.

The square of the period of a pendulum is related to the bob's mass.

The period of a pendulum is not related to the mass of the bob.

The period of a pendulum is related to the length of the string.

@Shane_B can u help pleasee? :)

shane_b · Answer

Look at the graph and note that no matter what the mass is, the period is about the same.  So what do you think ? :)

the first one? @Shane_B

is that correct?

@Shane_B thanks so much for your help on the other problem :) can u help with this please?

I thought I helped with this one already?  The graph shows that the period of the pendulum doesn't really change even if you change the mass (note that the graph is basically a line).  The only answer that fits that is:
"The period of a pendulum is not related to the mass of the bob."

This is a fact in physics...mass doesn't affect the period of a pendulum.
