Practise distinguishing light, critical and heavy damping, sketching displacement-time graphs and relating damping to continuing or decaying oscillations.
An object is suspended from a vertical spring as shown in Fig. 3.1.

Fig. 3.1
The object is displaced vertically and then released so that it oscillates, undergoing simple harmonic motion.

Fig. 3.2 shows the variation with displacement x of the energy E of the oscillations.
Fig. 3.2
The kinetic energy, the potential energy and the total energy of the oscillations are each represented by one of the lines P, Q and R .
State, with a reason, the type of damping that the card introduces into the system.
light damping because the amplitude of oscillations gradually reduces
or
light damping because the system still oscillates
