SPAU 3304 Exam 1 ACTUAL Exam
Questions and CORRECT Answers
force - CORRECT ANSWER - push or pull
what is force measured by - CORRECT ANSWER - the effect on an object
speed - CORRECT ANSWER - distance per time (speech rate)
ex. words per minute
velocity - CORRECT ANSWER - speed with direction (mandibular movement)
uniform motion - CORRECT ANSWER - constant velocity
ex. second hand on a clock goes in a constant speed and same direction in the circle
acceleration - CORRECT ANSWER - speed up
deceleration - CORRECT ANSWER - slows down
Newtons first law of motion - CORRECT ANSWER - an object will accelerate or
decellerate only if acted upon by an outside force
what two concepts does newtons first law introduce? - CORRECT ANSWER - force and
inertia
law of inertia - CORRECT ANSWER - tendency for an object to resist change in motion
,Newtons second law of motion - CORRECT ANSWER - acceleration is directly
proportional to the net force and inversley proportional to the objects mass
Force=? - CORRECT ANSWER - mass*acceleration
the greater the mass= - CORRECT ANSWER - slower the acceleration
the smaller the mass= - CORRECT ANSWER - the faster it will accelerate
newtons third law of motion - CORRECT ANSWER - for every action (force), there is an
equal and opposite reaction
ex. hammer hitting a nail, for the action theres a reaction of the nail going into the wood
momentum= - CORRECT ANSWER - mass*velocity
work - CORRECT ANSWER - a force is exerted over somedistance
unit of measurement for work - CORRECT ANSWER - Juule
juule - CORRECT ANSWER - amount of energy when a force of 1 newton is exerted for a
distance of 1 meter
energy - CORRECT ANSWER - ability to do work
power - CORRECT ANSWER - rate at which work is done
watt= - CORRECT ANSWER - 1 joule/sec.
, phases of matter - CORRECT ANSWER - solid,liquid,gas
density - CORRECT ANSWER - describes how closely packed together atoms/molecules
are in a material
stiffness - CORRECT ANSWER - degree of resistance to deformation
elasticity - CORRECT ANSWER - ability to spring back after deformation
pressure - CORRECT ANSWER - force per unit of area
exerted outward by fluid inside the container
ex. air in soccer ball is pushing on the material, so a lot of pressure
units of pressure measurement - CORRECT ANSWER - kilopascal and cm. of water
pressure
sound (psychological def) - CORRECT ANSWER - act of hearing something, an auditory
experience
sound (physical def) - CORRECT ANSWER - series of molecule disturbances in an elastic
medium(such as air)
acoustics - CORRECT ANSWER - study of the physics of sound
psychoacoustics - CORRECT ANSWER - study of the relationship between physical
properties and our perception of these properties
sound - CORRECT ANSWER - a condition of disturbances of particles in a medium
