حركة توافقية بسيطة
حركة توافقية بسيطة
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 ...

خصائص الحركة التوافقية البسيطة
The key characteristic of the simple harmonic motion is that the acceleration of the system and, therefore, the net force are proportional to the ...

التذبذبات حول وضع التوازن
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 ...

الطاقة في الحركة التوافقية البسيطة
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 ...

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 ...
حركة توافقية بسيطة وحركة دائرية موحدة
حركة توافقية بسيطة وحركة دائرية موحدة
While simple harmonic motion and uniform circular motion may be two separate concepts, they correlate and interlink with each other. Simple harmonic ...

حل المشكلات: الطاقة في الحركة التوافقية البسيطة
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 ...

البندول البسيط
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 ...
البندول الالتوائي
البندول الالتوائي
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 ...
البندول المادي
البندول المادي
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 ...
قياس التسارع بسبب الجاذبية
قياس التسارع بسبب الجاذبية
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 ...
التذبذبات المخمدة
التذبذبات المخمدة
In the real world, oscillations seldom follow true simple harmonic motion. A system that continues its motion indefinitely without losing its amplitude is ...
أنواع التخميد
أنواع التخميد
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, ...
التذبذبات القسرية
التذبذبات القسرية
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 ...

مفهوم الرنين وخصائصه
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 ...
