PHYSICS 1
Mass Spring Systems
Part 1:
(a) In the mass-spring system, the mass always acts on the spring which compresses as
well as stores the energy. In this way, the spring releases above energy back towards
the mass. When the process occurs, the mass will be jumped and bounced back into
the air, over and over, unless energy is dissipated by any friction. Hence, the damper
is used as a device which resists the springs’ motion in the opposite direction
(Jarrousse, 2014).

On the other hand, the natural frequency of vibration of the mass-spring system in the
absence of the opposing force of the damper (Jarrousse, 2014). The natural frequency
is the frequency that gets to a point in which the system resonates. Therefore, in the
absence of a damper, the mass will continue oscillating at a specific frequency termed
as natural frequency (Lumen Learning, 2020).
In order to determine the natural frequency of the given mass-spring system:
Formula (Jarrousse, 2014):
F= ω /2π
Here, ω = √(k / m)
Thus, natural frequency: f = √(k / m) ÷ 2π
f = √(12500 N/m / 750 kg) ÷ 2π
f = √(16.66 s−2) ÷ 2π
f =4.081 ÷ 2π
f = 0.6495 Hz
Thus, for the given case, the natural frequency is 0.6495 Hz, which means the system
would oscillate just over one and a half times per second.
