Oscillations

Question 1

Define Free oscillation

Answer 1

An object undergoes free oscillation when its restoring force is the only force acting on it, causing it to oscillate about its equilibrium position at its natural frequency.

Question 2

Define damped oscillations

Answer 2

Damping is the process whereby energy is dissipated from an oscillating object.

Question 2

Define resonance

Answer 2

Resonance is the phenomenon that occurs when the driving frequency of the driver is the same as the natural frequency of the driven system resulting in maximum transfer of energy from driver to driven system. Driven system will thus have maximum amplitude of oscillation.

Question 2

Define SMH

Answer 2

SMH is defined as the periodic motion of an object about the equilibrium position in which its acceleration is proportional to the displacement of the object and it always acts in the opposite direction to its displacement. (also known as the restoring force)
