Oscillations

단순 조화 운동
단순 조화 운동
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 ...
Simple Harmonic Motion의 특성
Simple Harmonic Motion의 특성
The key characteristic of the simple harmonic motion is that the acceleration of the system and, therefore, the net force are proportional to the ...
Equilibrium Position에 대한 진동
Equilibrium Position에 대한 진동
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 ...
단순 조화 운동의 에너지
단순 조화 운동의 에너지
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 ...
Spring-Mass System의 주파수
Spring-Mass System의 주파수
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 ...
단순 조화 운동(Simple Harmonic Motion)과 균일한 원운동(Uniform Circular Motion)
단순 조화 운동(Simple Harmonic Motion)과 균일한 원운동(Uniform Circular Motion)
While simple harmonic motion and uniform circular motion may be two separate concepts, they correlate and interlink with each other. Simple harmonic ...
문제 해결: 단순 조화 운동의 에너지
문제 해결: 단순 조화 운동의 에너지
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 ...
단순 진자
단순 진자
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 ...
비틀림 진자
비틀림 진자
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 ...
물리적 진자
물리적 진자
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 ...
중력으로 인한 가속도 측정
중력으로 인한 가속도 측정
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 ...
감쇠 진동
감쇠 진동
In the real world, oscillations seldom follow true simple harmonic motion. A system that continues its motion indefinitely without losing its amplitude is ...
댐핑의 종류
댐핑의 종류
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, ...
강제 진동
강제 진동
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 ...
공명의 개념과 그 특성
공명의 개념과 그 특성
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 ...
