Oscillations

Prosty ruch harmoniczny
Prosty ruch harmoniczny
Simple harmonic motion is the name given to oscillatory motion for a system where the net force can be described by Hooke's law. If the net force can ...
Charakterystyka prostego ruchu harmonicznego
Charakterystyka prostego ruchu harmonicznego
The key characteristic of the simple harmonic motion is that the acceleration of the system and, therefore, the net force are proportional to the ...

Oscylacje wokół pozycji równowagi
Stability is an important concept in oscillation. If an equilibrium point is stable, a slight disturbance of an object that is initially at the stable ...
Energia w prostym ruchu harmonicznym
Energia w prostym ruchu harmonicznym
To determine the energy of a simple harmonic oscillator, consider all the forms of energy it can have during its simple harmonic motion. According to ...

Częstotliwość układu sprężyna-masa
One interesting characteristic of the simple harmonic motion (SHM) of an object attached to a spring is that the angular frequency, and the period and ...
Prosty ruch harmoniczny i jednostajny ruch kołowy
Prosty ruch harmoniczny i jednostajny ruch kołowy
While simple harmonic motion and uniform circular motion may be two separate concepts, they correlate and interlink with each other. Simple harmonic ...

A simple pendulum consists of a small diameter ball suspended from a string, which has negligible mass but is strong enough to not stretch. In our daily ...

A torsional pendulum involves the oscillation of a rigid body in which the restoring force is provided by the torsion in the string from which the rigid ...

Tłumione oscylacje
In the real world, oscillations seldom follow true simple harmonic motion. A system that continues its motion indefinitely without losing its amplitude is ...

If the amount of damping in a system is gradually increased, the period and frequency start to become affected because damping opposes, and hence slows, ...
Oscylacje wymuszone
Oscylacje wymuszone
When an oscillator is forced with a periodic driving force, the motion may seem chaotic. The motions of such oscillators are known as transients. After ...
Pojęcie rezonansu i jego charakterystyka
Pojęcie rezonansu i jego charakterystyka
If a driven oscillator needs to resonate at a specific frequency, then very light damping is required. An example of light damping includes playing piano ...
