Class 11PhysicsOscillationsDifferent types of oscillations (Free, Damped, Forced Oscillation and Resonance)
MediumSometimes when the speed of a vehicle is increased,its body starts to bounce. Why?
(N/A) When the speed of a vehicle increases,the frequency of the periodic impulses received from the rough road surface increases.
When this frequency matches the natural frequency of the vehicle's suspension system,the phenomenon of resonance occurs.
Due to resonance,the amplitude of the oscillations becomes very large,causing the vehicle to bounce significantly.
