In the context of the physical pendulum, what additional factor (not present in a simple pendulum) affects its oscillation frequency?
Tension in the string
Air resistance
Moment of inertia

Which formula correctly represents the angular frequency (𝜔) of a physical pendulum?
𝜔 = √(k/m)
𝜔 = √(g/L)
𝜔 = √(I/mg)
𝜔 = √(mgd/I)
In the spring oscillator setup, why is it important to zero the force sensor before each trial?
To reduce air resistance effects
To eliminate the influence of previous mass measurements
To calibrate the rotary motion sensor
To prevent the mass from oscillating too fast
Which method is used to determine the spring constant k in the lab?
Measuring the amplitude of oscillation
Calculating it from the force-displacement graph
Using the relationship between frequency and mass
Estimating from the maximum extension
For the configuration with two cylinders at opposite ends of the rod in the physical pendulum experiment, what is the expected value of dd?
Zero
Half the rod length
Equal to the distance from the pivot to the rod's center of mass
Equal to the radius of the cylinders
In the spring oscillator experiment, what is the purpose of plotting T^2 vs. mass?
To measure the force of gravity
To determine the damping constant
To find the spring constant k
To calculate the center of mass of the system
What increases when the masses on a physical pendulum move farther from the pivot?
Frequency
Mass
Center of mass distance
Spring constant
