Question

what is the phase difference between driving force and velocity of oscillator​

Answer 1

Answer:

the velocity is the derivative of position, so there is a π/2 phase shift between position and velocity. At resonance (when ω=ω0), ϕ=−π/2 and the force and velocity

Answer 2

Answer:

Of course the velocity is the derivative of position, so there is a π/2 phase shift between position and velocity. At resonance (when ω=ω0), ϕ=−π/2 and the force and velocity are in phase (this is how you get the optimal coupling of power into the oscillator).
