Phys 161 Lab 7

What physical quantity is determined using the spring oscillator in Part 1 of the experiment?

•  Moment of inertia

• Angular velocity

• Spring constant

• Acceleration due to gravity

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

• Amplitude of oscillation

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 kk 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
