Oscillations

Question 1

Explain resonance in terms of energy transfer in an oscillatory system.

Answer 1

Resonance occurs when driving frequency of external oscillatory system is equal to the natural frequency of the oscillating system. Maximum energy is transferred and the oscillating system oscillates with maximum amplitude.

Question 2

What is amplitude?

Answer 2

It is maximum displacement from the equilibrium position.

Question 3

What is frequency?

Answer 3

It is number of complete cycles per unit time.

Question 4

What is period?

Answer 4

It is time taken to complete one oscillation.

Question 5

Define simple harmonic motion?

Answer 5

It is an oscillatory motion of a particle whose acceleration is directly proportional to its displacement from the equilibrium position and this acceleration is directed towards that position.
