IB Physics HL Resonance
/A tutorial sheet of resonance questions from the Engineering Physics option is given below.
- An oscillator is subject to no damping. Describe its motion if its natural frequency is 2π and the driving frequency is π.
- An oscillator undergoes damped oscillations. Is the frequency of the damped oscillations the same as the undamped oscillations?
- An oscillator has a natural frequency π and is subject to a damping acceleration that is proportional to its velocity with a proportionality constant 2k. Write down the condition for (a) damped oscillations (b) critically damped oscillations (c) overdamping.
- An oscillator has damping. When the damping is increased does the frequency at which the maximum forced oscillations occur increase or decrease? Give a reason.
