Practise distinguishing light, critical and heavy damping from displacement-time behaviour and comparing settling time, overshoot and oscillation in practical systems.
This question is in two parts. Part 1 is about ideal gases and specific heat capacity. Part 2 is about simple harmonic motion and waves.
Part 1 Ideal gases and specific heat capacity
Simple harmonic motion and waves
W in (a) is immersed in a beaker of oil. As a result of this immersion the oscillations of W are critically damped. Describe what is meant by critically damped.
(the frictional force on W is such that) motion rapidly dies away/rapidly stops/stops in the minimum time;
without completing an oscillation / without overshooting (equilibrium position);
