M5- C17

Question 1

Isochronous oscillator

Answer 1

An oscillator that has the same period regardless of amplitude

Question 2

dampening

Answer 2

An oscillation is dampened when an external force that acts on the oscillator has the effect of reducing the amplitude of its oscillations

Question 3

Light dampening

Answer 3

Dampening that occurs when the damping forces are small and the period of the oscillations is almost unchanged

Question 4

Heavy dampening

Answer 4

Dampening that occurs when the dampening forces are large and the period of the oscillations increases slightly with the rapid decrease in amplitude

Question 5

Free oscillation

Answer 5

The motion of a mechanical system displaced from its equilibrium position and then allowed to oscillate without any external forces

Question 6

Natural frequency

Answer 6

The frequency of a free oscillation

Question 7

Forced oscillation

Answer 7

An oscillation in which a periodic driver force is applied to an oscillator

Question 8

Driving frequency

Answer 8

The frequency with which the periodic driver force is applied to a system in forced oscillation

Question 9

Resonance

Answer 9

The increase in amplitude of a forced oscillation when the driving frequency matches the natural frequency of the oscillating system
