Oscillation

Question 1

Define 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 that point

Question 2

What is angular frequency

Answer 2

Angular frequency is the rate of change of phase angle of the oscillation and is equal to he product of 2pie and its frequency

Question 3

What is free oscillation

Answer 3

A free oscillation occurs when an object oscillates with no restrictive and driving force acting on it.

Question 4

What is damping

Answer 4

Damping is the process whereby energy is removed from an oscillating system

Question 5

What is forced oscillation

Answer 5

Forced oscillated are produced when a body is subjected to a period external driving force

Question 6

What is resonance

Answer 6

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

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