Relationship between Mass and InertiaANALYSING DATA :- Draw a graph of f against m

DISCUSSION :- State the quantity used to represent the inertia in this activity? State the relationship between m and f.- What is the relationship between inertia and mass- Estimate the frequency of the oscillation when the mass is 45 g, show on the graph how you get the value.
