Inertia

The property of a system to remain at equilibrium until acted upon by an external force.

Momentum

A property of a moving object that describes how hard it is to stop, which is determined by its mass and speed.

States of Matter

The three forms that matter can take: solid, liquid, and gas.

Solid

A state of matter where the material maintains a definite shape and volume at a constant temperature.

Liquid

A state of matter that maintains a constant volume but takes the shape of its container.

Gas

A state of matter that expands to fill its container and does not have a definite shape or volume.

Wave

A disturbance that travels through a medium.

Longitudinal Wave

A type of wave where displaced particles of the medium move parallel to the wave's motion.

Transverse Wave

A type of wave where the displaced particles move perpendicular to the motion of the wave.

Frequency

The number of times a wave's cycle occurs per second, measured in Hertz (Hz).

Wavelength

The distance traveled by one cycle of a wave, inversely related to frequency.

Amplitude

The height or strength of a wave, related to its intensity.

Resonance

The increase in the amplitude of an object's vibration when a force is applied at its natural frequency.

Vocal Folds

Structures located in the larynx that can be opened or closed to produce sound.

Harmonics

Higher resonant frequencies that are multiples of the fundamental frequency (f0).

Viscoelastic Properties

Properties that describe how the vocal fold tissues return to their original shape after being displaced.

Mucosal Wave

The wave traveling across the surface of the vocal folds during voicing.

Body/Cover Model

A model grouping the layers of the vocal folds into three parts: Cover, Transition, and Body.

Elasticity

The ability of the vocal fold tissues to spring back after being displaced.

Stiffness

The measure of how much force is needed to displace an object from its equilibrium position.

Wavelength

The distance traveled by one cycle of a wave, inversely related to frequency.

Amplitude

The height or strength of a wave, related to its intensity.

Resonance

The increase in the amplitude of an object's vibration when a force is applied at its natural frequency.

Vocal Folds

Structures located in the larynx that can be opened or closed to produce sound.

Harmonics

Higher resonant frequencies that are multiples of the fundamental frequency (f0).

Viscoelastic Properties

Properties that describe how the vocal fold tissues return to their original shape after being displaced.

Mucosal Wave

The wave traveling across the surface of the vocal folds during voicing.

Periodic Waves

Waves that repeat at regular intervals, characterized by consistent frequency and wavelength.

Reflection Wave

The wave that occurs when a wave bounces back after hitting a barrier, changing direction but retaining its speed.

Impact on Frequency of Object

The alterations to the frequency of an object when it vibrates, affected by factors like tension, length, and mass.

1st Harmonic

The lowest frequency produced by a vibrating object, also known as the fundamental frequency.

2nd Harmonic

A frequency that is twice that of the first harmonic, producing a sound that is an octave higher.

Resonator in Sound

An object or system that amplifies or sustains vibrations by matching its resonant frequency with the input frequency.

Boyle's Law

A principle stating that the pressure of a gas is inversely proportional to its volume when temperature remains constant.

Diaphragm

A dome-shaped muscle located beneath the lungs that plays a vital role in breathing by contracting and relaxing.

Lungs Composition

The lungs are primarily made up of alveoli, bronchi, and lung tissue, responsible for gas exchange.

Inhalation Process

The process of breathing in, where the diaphragm contracts, expanding the thoracic cavity, creating a negative pressure that draws air into the lungs.

Lobes of Lungs

The lungs are divided into lobes: the right lung has three lobes, while the left lung has two lobes to accommodate the heart.
