results in the production of linguistically meaningful sounds (phonemes) - correct answer ✔✔Speech
production
Process of producing sound waves that are audible to the human ear - correct answer ✔✔Speech
production
The study of the physics of sound - correct answer ✔✔acoustics

that cause the movements - correct answer ✔✔Kinematics
the study of the forces that cause movement - correct answer ✔✔dynamics
the study of the relationship between physical properties of a phenomenon and our perception of those
properties - correct answer ✔✔psychoacoustics
The generation of sound waves by vibration of the vocal folds which are then modified by the vocal tract
- correct answer ✔✔voice production
production of sound waves by vibration of the vocal folds - correct answer ✔✔voice
production of phonemes by structures of the vocal tract above the larynx, particularly the oral cavity -
correct answer ✔✔speech
What is the role of basic research? - correct answer ✔✔provides conceptual framework that helps you
interpret and explain what you observe
,What international system of measurement do most countries around the world use? - correct answer
✔✔metric system
A push or pull - correct answer ✔✔force
relationship distance-time, distance per time - correct answer ✔✔speed
What has the same numerical value as speed but also contains info about the direction of movement? -
correct answer ✔✔velocity
_________ = magnitude of the velocity - correct answer ✔✔speed
What is uniform motion? - correct answer ✔✔when the speed of an object is constant in a single
direction
speed up (change in velocity as a function of time) - correct answer ✔✔acceleration
slow down - correct answer ✔✔deceleration
three laws that describe how objects behave when acted upon by an outside force - correct answer
✔✔newton's laws of motion
A moving object will continue moving and a stationary object will remain at rest, unless acted upon by an
outside force - correct answer ✔✔Newton's 1st Law of Motion (or inertial law)
When a net force act on an object, the object accelerates in the same direction as the force - correct
answer ✔✔Newton's 2nd Law of Motion
Acceleration is __________ proportional to the _____ force - correct answer ✔✔directly; net
, Acceleration is _________ proportional to the __________ of an object - correct answer ✔✔inversely;
mass
The _________ the force, the greater the acceleration, and the larger the mass, the ________ the
acceleration - correct answer ✔✔larger; smaller
unit of force? - correct answer ✔✔newton (N)
For every action (force), an equal and opposite reaction (force) occurs - correct answer ✔✔Newton's 3rd
Law of Motion
The greater either the ______ or the _______ of an object is, the more difficult it is to stop or change
direction - correct answer ✔✔mass; speed
Like velocity, ____________ has both magnitude and direction - correct answer ✔✔momentum
Tendency for an object to resist movement - correct answer ✔✔inertia
________ must be overcome to achieve forward or backward momentum - correct answer ✔✔inertia
Performed whenever a force is exerted over some distance - correct answer ✔✔work
Unit of measurement for work? - correct answer ✔✔joule
Ability to do work - correct answer ✔✔energy
Rate at which work is done (or energy is expended) - correct answer ✔✔power
Unit of measurement for power? - correct answer ✔✔watt (watt = 1 joule/sec)
