Question 1

[Maximum number: 1]

An object is suspended from a vertical spring as shown in Fig. 3.1.

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 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 the cause of damping.
