Does mass affect the period of a pendulum?

no, just g and L

Yes, the mass of a pendulum does affect its period. The period of a pendulum is the time it takes for it to complete one full swing or oscillation. The period depends on two main factors: the length of the pendulum and the acceleration due to gravity.

To understand how mass affects the period of a pendulum, we need to consider the equation of motion for a simple pendulum:

T = 2π√(L/g)

Where:
T = period of the pendulum
π = pi (approximately 3.14159)
L = length of the pendulum
g = acceleration due to gravity

As you can see from the equation, mass does not explicitly appear in the equation. The period is only dependent on the length of the pendulum and the acceleration due to gravity. Hence, mass does not directly affect the period of a pendulum.

However, it is important to note that the mass of the pendulum can indirectly affect the period through its impact on the center of gravity. If the mass is concentrated at the end of the pendulum, it would shift the center of gravity towards the end, which would slightly increase the effective length of the pendulum. This increase in length would result in a slightly longer period. Conversely, if the mass is concentrated towards the pivot point, it would decrease the effective length and result in a slightly shorter period.

In summary, while mass does not directly affect the period of a pendulum, the distribution of mass along the pendulum can have a minor, indirect effect on the period by influencing the effective length of the pendulum.
