Oscillations

Простое гармоническое движение
Простое гармоническое движение
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 ...
Характеристики простого гармонического движения
Характеристики простого гармонического движения
The key characteristic of the simple harmonic motion is that the acceleration of the system and, therefore, the net force are proportional to the ...
Колебания вокруг равновесного положения
Колебания вокруг равновесного положения
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 ...
Энергия в простом гармоническом движении
Энергия в простом гармоническом движении
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 ...

Частота системы пружина-масса
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 ...
Простое гармоническое движение и равномерное круговое движение
Простое гармоническое движение и равномерное круговое движение
While simple harmonic motion and uniform circular motion may be two separate concepts, they correlate and interlink with each other. Simple harmonic ...
Решение проблем: энергия в простом гармоническом движении
Решение проблем: энергия в простом гармоническом движении
Simple harmonic motion (SHM) is a type of periodic motion in time and position, in which an object oscillates back and forth around an equilibrium ...
Простой маятник
Простой маятник
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 ...
Торсионный маятник
Торсионный маятник
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 ...
Физический маятник
Физический маятник
When a rigid body is hanging freely from a fixed pivot point and is displaced, it oscillates similar to a simple pendulum and is known as a physical ...
Измерение ускорения под действием силы тяжести
Измерение ускорения под действием силы тяжести
Consider a coffee mug hanging on a hook in a pantry. If the mug gets knocked, it oscillates back and forth like a pendulum until the oscillations die ...
Затухающие колебания
Затухающие колебания
In the real world, oscillations seldom follow true simple harmonic motion. A system that continues its motion indefinitely without losing its amplitude is ...
Виды демпфирования
Виды демпфирования
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, ...
Вынужденные колебания
Вынужденные колебания
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 ...
Понятие резонанса и его характеристики
Понятие резонанса и его характеристики
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 ...
