Quiz on Harmonic Motion

What is harmonic motion?

• Any periodic motion.

• Oscillatory motion that can be described by a sine or cosine function.

• Circular motion.

• Motion with constant velocity.

Which physical quantity characterizes the maximum displacement from the equilibrium position in harmonic motion?

• Period

• Frequency

• Amplitude

• Phase

What is the period of oscillation?

• The time taken for one complete oscillation.

• The distance traveled in one oscillation.

• The number of oscillations per unit time.

• The angle of rotation of the phase per unit time.

What is the formula that relates the period and frequency of oscillation?

• T = 2πf

• f = 2πT

• T = f

• T = 1/f

What is the phase of oscillation?

• The maximum displacement from the equilibrium position.

• The initial position of the oscillating object at time t=0.

• The time taken for one complete oscillation.

• The number of oscillations per unit time.

What does the graph of harmonic motion look like?

• A straight line

• A sine wave

• A parabola

• An exponential curve

What does the amplitude determine in the equation of harmonic motion?

• The maximum displacement from the equilibrium position

• The period of oscillation

• The frequency of oscillation

• The initial phase of oscillation

How are the period and frequency of oscillation related?

• The period is directly proportional to the frequency.

• The period is inversely proportional to the frequency.

• The period and frequency are not related.

• The period is equal to the frequency.

What is resonance?

• A phenomenon where the amplitude of forced oscillations increases sharply when the frequency of the external force matches the natural frequency of the system.

• The damping of oscillations over time.

• The transition from one type of oscillation to another.

• The change in the direction of oscillations.

What are some practical applications of harmonic motion?

• In clocks, pendulums, musical instruments.

• Only in physics experiments.

• Have no practical applications.

• Only in electrical engineering.
