Which of the following is a characteristic of simple harmonic motion?

• The motion is always in a straight line.

• The restoring force is constant regardless of displacement.

• The motion occurs at a constant speed without acceleration.

• The restoring force is proportional to the displacement.

In damped oscillations, what happens to the amplitude over time?

• The amplitude decreases over time.

• The amplitude oscillates without change over time.

• The amplitude increases over time.

• The amplitude remains constant over time.

What type of damping occurs when the oscillation stops quickly?

• Over-damping

• Free oscillation

• Under-damping

• Critical damping

What is the term for the maximum amplitude of oscillation at resonance?

• maximum frequency

• resonant amplitude

• oscillation threshold

• peak amplitude

How does the frequency of a driving force affect resonance?

• Resonance occurs only at low frequencies regardless of the driving force.

• The frequency of a driving force has no effect on resonance.

• A higher frequency always decreases the amplitude of resonance.

• The frequency of a driving force affects resonance by determining whether it matches the system's natural frequency, leading to increased amplitude when matched.

In wave properties of oscillations, what is the term for the distance between two consecutive crests?

• Frequency

• Period

• Amplitude

• Wavelength

What is the effect of increasing damping on the frequency of oscillation?

• Increasing damping causes oscillation to stop completely.

• Increasing damping increases the frequency of oscillation.

• Increasing damping has no effect on the frequency of oscillation.

• Increasing damping decreases the frequency of oscillation.

Which of the following best describes resonance phenomena?

• Resonance is the same as interference.

• Resonance occurs when a system is driven at its natural frequency.

• Resonance occurs only in electrical circuits.

• Resonance can only happen in vacuum conditions.

How does energy transfer occur in forced oscillations?

• Energy is transferred solely by gravitational pull.

• Energy transfer in forced oscillations occurs through the work done by an external periodic force.

• Energy transfer occurs only through internal damping forces.

• Energy transfer happens without any external influence.

What is the significance of the natural frequency in oscillatory systems?

• Natural frequency determines the color of the system.

• Natural frequency is irrelevant in mechanical systems.

• The natural frequency is crucial for understanding system behavior, resonance, and stability in oscillatory systems.

• Natural frequency only affects electrical circuits.
