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
An object moving in this path shape is what defines Uniform Circular Motion.
What is a circle?
We call this kind of energy "stored energy".
What is Potential Energy
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)?
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)?
This is how we describe what happens to energy of a falling object
What is as an object falls, its potential energy decreases while its kinetic energy increases, conserving the total mechanical energy?
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?
Multiplying these two wave properties calculates its velocity?
What are frequency and wavelength
Acceleration multiplied by mass equals this.
What is Force?
The centripetal force of an object also includes this dimension of the obect.
What is it's mass?
A description of how height affects potential energy?
What is the higher an object is, the greater its potential energy, as it is directly proportional to height?
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?
These are mechanical waves in which the amplitude of the wave is parallel to the direction of energy travel.
What is a longitudinal or compression wave?
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)?
This is the equation for PE.
What is mass (x) gravity acceleration (9.8) (x) height?
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
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?
As the radius of the circle increases, the centripetal acceleration and centripetal force must do this.
What is decrease?
These two (2) variables determine potential energy in a spring or compression.
What is the spring (or force) constant, k, and the amount of stretch or compression squared, x2?
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?
