Movimento harmônico simples
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 ...
Características do Movimento Harmônico Simples
The key characteristic of the simple harmonic motion is that the acceleration of the system and, therefore, the net force are proportional to the ...
Oscilações em Torno de uma Posição de Equilíbrio
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 em Movimento Harmônico Simples
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 ...
Frequência do sistema massa-mola
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 ...
Movimento Harmônico Simples e Movimento Circular Uniforme
While simple harmonic motion and uniform circular motion may be two separate concepts, they correlate and interlink with each other. Simple harmonic ...
Resolução de Problemas: Energia em Movimento Harmônico Simples
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 ...
Pêndulo Simples
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 ...
Pêndulo de Torção
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 ...
Pêndulo Físico
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 ...
Medindo a aceleração devido à gravidade
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
...
Oscilações Amortecidas
In the real world, oscillations seldom follow true simple harmonic motion. A system that continues its motion indefinitely without losing its amplitude is ...
Tipos de Amortecimento
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, ...
Oscilações Forçadas
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 ...
Conceito de ressonância e suas características
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 ...
