Quiz on Oscillations and Simple Harmonic Motion

What is oscillation?

• A one-time movement

• A random movement

• A linear motion

• A repetitive or cyclical variation of a quantity

What is a restoring force?

• A force that increases displacement

• A force that causes damping

• A force that brings an oscillating body back to equilibrium

• A force that opposes motion

What characterizes a damped oscillator?

• It oscillates indefinitely

• It experiences resistive forces during oscillation

• It has a constant amplitude

• It has no resistive forces

In SHM, what is the relationship between acceleration and displacement?

• Acceleration is inversely proportional to displacement

• Acceleration is proportional to displacement and in the same direction

• Acceleration is proportional to displacement and in the opposite direction

• Acceleration is independent of displacement

What happens to the oscillations of a free oscillator?

• They are always damped

• They do not return to equilibrium

• They are influenced by external forces

• They are only influenced by the restoring force

What is resonance?

• A state of no motion

• A random oscillation

• Maximum amplitude when the driving frequency matches the natural frequency

• A type of damping

What effect does damping have on an oscillator?

• It increases the amplitude

• It makes the oscillator move faster

• It decreases the amplitude over time

• It has no effect

What is a characteristic of a harmonic oscillator?

• Its restoring force is not proportional to displacement

• It does not oscillate

• Its restoring force is proportional to displacement

• It only oscillates in one direction

What is the formula for the restoring force in a mass-spring system?

• F = mv^2

• F = ma

• F = kx

• F = mg

What is the effect of increasing damping on the amplitude-frequency curve?

• The peak shifts to a higher frequency

• The peak shifts to a lower frequency

• The peak becomes sharper

• The peak remains unchanged
