Oscillations

Question 1

Simple Harmonic Motion

Answer 1

Simple harmonic motion is defined as the motion of a particle about a fixed point such that its acceleration is proportional to its displacement from the fixed point and is always directed towards the point

Question 2

Angular Frequency

Answer 2

Angular frequency is defined as the rate of change of phase angle of the oscillation, and is equal to the product of 2π and its frequency

Question 3

Amplitude

Answer 3

Amplitude is the magnitude of the maximum displacement of the particle from its equilibrium position

Question 4

Frequency [Oscillations]

Answer 4

Frequency is the number of oscillations per unit time

Question 5

Period [Oscillations]

Answer 5

Period is the time taken to complete one oscillation

Question 6

Resonance

Answer 6

Resonance occurs when a system responds at maximum amplitude to an external driving force

This occurs when the frequency of the driving force is equal to the natural frequency of the driven system
