Damping and Oscillation Concepts

What is the measure of the speed of an object's angular rotation called?

• Linear Speed

• Centripetal Force

• Angular Speed

• Resonance

Which force always acts towards the centre of an object's rotation in circular motion?

• Gravitational Force

• Centripetal Force

• Frictional Force

• Damping Force

What is the form of damping that reduces the displacement of an oscillating object to its equilibrium position in the quickest time possible without further oscillation?

• Overdamping

• Underdamping

• Critical Damping

• Free Vibration

Which of the following best describes resonance?

• When the amplitude of oscillation is always zero

• When the frequency of oscillations matches the natural frequency of the system

• When the system is overdamped

• When the system is at rest

What is a radian?

• A unit of force

• A unit of energy

• A unit of angle

• A unit of frequency

Which type of vibration occurs without a driving force and at the object's natural frequency?

• Forced Vibrations

• Free Vibrations

• Resonance

• Damping

What happens to the amplitude of oscillation in a system experiencing damping?

• It increases

• It remains constant

• It decreases

• It becomes zero instantly

In simple harmonic motion, how is the acceleration of an object related to its displacement?

• Directly proportional and in the same direction

• Inversely proportional and in the opposite direction

• Directly proportional and in the opposite direction

• Unrelated

Which type of damping takes longer for the system to return to equilibrium than critical damping?

• Overdamping

• Underdamping

• Resonance

• Free Vibrations

What is the main consequence of damping in an oscillating system?

• The frequency increases

• The amplitude of oscillation will decrease

• The system gains energy

• The system stops moving instantly
