Waves
This property of a wave is expressed in Hertz.
What is frequency?
This the equation for acceleration as defined by N2LM.
What is
a = F/m
What is the Doppler Effect?
Two waves can occupy the same space because they are NOT this.
What is matter?
For an object to have KE, it MUST have this.
What is velocity?
This is how long it takes for one wave to pass a given point.
What is period (T)?
Two types of interference patterns are this.
What is constructive and destructive?
These two wave properties are inverses of each other.
What are the period and frequency?
The acceleration of a less massive object requires less of this than a more massive object.
What is force?
Centripetal acceleration is a function of these two (2) variables.
What is velocity and radius (of the circular path)?
When two waves meet, and they cancel each other out, we call it this
What is destructive interference?
The equation that is used determine the amount of KE an object has.
What is (.5) x mass x velocity2?
These are the two types of mechanical waves we discuss.
What are longitudinal (compression) and transverse waves?
This is created by a shock wave that is moving faster than the speed of sound.
What is sonic boom?
Multiplying these two wave properties calculates its velocity?
What are frequency and wavelength
Acceleration multiplied by mass equals this.
What is Force?
A medium allows this type of wave to propagate
What is a mechanical wave?
Hearing a firetruck siren increase in pitch as it approaches is due to this phenomenon.
What is the Doppler Effect?
A Formula One (F1) car and a fully loaded dump truck have the same velocity. But the dump truck has more KE because it has a lot more of this.
What is mass?
This is what is called through which waves travel.
What is a medium?
If the frequency of a vibrating object gets doubled than this happens to its period.
What is cut in half?
These ubiquitous devices are worn by travelers because of their destructive wave interference technology.
What are noise-cancelling headphones?
This wave property is symbolized with Lambda
lambda
What is wavelength?
A Formula 1 car and a dump truck both produce 800 horsepower of force, but the Formula 1 car accelerates much faster because of this.
What is the less mass of the F1 car?
When the velocity of an object is tripled, then both its centripetal force and acceleration increase by this much.
What is nine times (9x)?
If two waves meet and form one, bigger wave, call it this type of interference.
What is constructive interference?
As a rock falls to the Earth, it gains KE due to gravitational acceleration, and its PE is getting less and less. This is because of the Law of this.
What is the Law of Conservation of Energy?
An earthquake creates this kind of mechanical wave.
What is a seismic wave? Or a transverse wave is acceptable
As a moving object makes a constant sound and moves toward an observer, the observer hears this.
What is an increasingly higher pitched sound
How many waves pass a given point per second?
What is frequency?
This force is responsible for an object's acceleration in freefall.
What is gravity?
A distance between two wave crests or troughs defines this.
What is wavelength?
Because of the apparent change in this, a baseball coach can find the velocity of his pitchers' fastball.
What is the (apparent) change in wave frequency?
The Law of Conservation of Energy states we can only do this and cannot do that.
What is we can only transform energy and we cannot create or destroy energy?
This is what creates a wave in the first place.
What is a vibration?
Astronomers are able to detect motion of celestial bodies by comparing these.
What are frequencies of light emitted?
