Vibrations, spring stiffnesses of vibrating systems is dealt with. These considerations are followed by the treatment of the free damped vibration of single-mass oscillators, whereby we have to distinguish between different cases of damping. This chapter concludes with the consideration of forced undamped and damped vibrations.

Principle of work and energy, conservation of energy,n a general definition of the concept of mechanical work, the principle of work and energy and the law of conservation of energy are introduced, whereby a distinction must be made between forces with potential and forces without potential.
