GENERAL PHYSICS 1 QUARTER 2 PART 1

What is the term for the time it takes to complete one full cycle of periodic motion?

• Frequency

• Amplitude

• Period

• Wavelength

Which of the following is an example of periodic motion?

• A ball rolling down a hill

• Earth’s rotation on its axis

• A car accelerating on a highway

• A glass falling off a table

In a simple pendulum, the frequency depends on:

• Mass of the bob

• Length of the string

• Amplitude of swing (large angles)

• Air resistance

For a spring-mass system, the frequency of oscillation increases if:

• The mass increases

• The spring constant increases

• The amplitude increases

• Gravity increases

In a physical pendulum, the restoring torque depends on:

• The pivot point and distribution of mass

• The color of the object

• The surface friction

• The amplitude only

The frequency of a simple pendulum will decrease if:

• The length of the string is shortened

• The acceleration due to gravity increases

• The length of the string is increased

• The mass of the bob is reduced

Which formula gives the frequency of oscillation for a spring-mass system?

• T=2πmk

• f=1/2π√(mk)

• f=k/2πm

• f=1/2πmk

A block of mass 0.25 kg is attached to a spring with a spring constant of 100 N/m and set into oscillation. What is the frequency of oscillation of the block-spring system?

• 1.0 Hz

• 2.0 Hz

• 3.0 Hz

• 3.18 Hz

A spring with a spring constant of 150 N/m is attached to a mass of 0.75 kg. What is the period of oscillation of the system?

• 0.34 s

• 0.41 s

• 0.45 s

• 0.52 s

A uniform rod of mass 10 kg is pivoted at one end. Its center of mass is 0.5 m from the pivot, and the moment of inertia about the pivot is 4.2 kg·m². What is the frequency of oscillation of the rod?

• 0.33 Hz

• 0.49 Hz

• 0.56 Hz

• 0.61 Hz
