Chapter 1 Vocab Flashcards
Speed
Distance travelled over a unit of time
Acceleration
Change in velocity per unit of time
Mass
Amount of matter in an object
Density
Mass per unit volume (p)
Weight
Force of gravity pulling an object to the earth
Pressure
Force per unit area, measured in units of pounds per square foot aka pascals
The most important concept in the study of waves and sound
Simple Harmonic Motion
Periodic Motion
Any motion that repeats itself
Simple Harmonic Motion (SMH)
A specific type of periodic motion that arises from an Equilibrium position and Linear Restoring Force
What two qualities are present in SMH
Equilibrium Position and Linear Restoring Force
Equilibrium position
The place where an object would remain at rest
Linear Restoring Force
A force is linearly proportional to the distance of the object from the equilibrium position.
A numerical example of a linear restoring force…
“if it requires 1 N of force to lift a mass 1 cm, it will require for 2 N to list it 2cm, etc. because its restoring force is linear.
A system w/ a force constant of 1N/cm obey’s what law…
Hooke’s Law
Amplitude
the max displacement of the mass (sound wave)
