Is the period of an oscillatory motion of a wave affected by the mass?

I did an experiment with a pendulum and we got to measure the time it took for 10 complete waves. Each time we added 50 grams more and so on. For the conclusion they are asking me if by adding more mass to the pendulum the period of the oscillatory motion changes, but I'm not sure because my results don't make sense at all.

Please help!Is the period of an oscillatory motion of a wave affected by the mass?A pendulum's motion is not "a wave". It isn't traveling anywhere in the long run, hence not a wave.



A pendulum's motion is called an oscillation, and each complete set of motion is called a cycle...and the time of a cycle is called the period.





The pendulum is interesting in the fact that mass of the bob both causes the restoring force AND the inertia. Because mass is proportional to each, mass 'cancels out'.





In oscillations in general, mass can affect the period. BUT, that is only the case if the restoring force is mass-independent, like in the block on spring vibration situation, where the spring stiffness sets the restoring force independent of the attached block's mass.
