What is a mechanical wave?
waves which propagate through a material medium (solid, liquid, or gas) at a wave speed which depends on the elastic and inertial properties of that medium
100
What is Newton's First Law of Motion?
an object in motion will stay in motion unless acted on by an outside force
100
What is kinetic energy?
when the object is in motion
100
What type of energy transformation is this?
You bite into a banana.
mechanical to chemical
100
What is transparent light?
light that passes straight through the object
200
How do transverse waves differ from longitudinal waves?
In a longitudinal wave the particle displacement is parallel to the direction of wave propagation
In a transverse wave the particle displacement is perpendicular to the direction of wave propagation
200
What is Newton's Second law of Motion?
the acceleration of an object is dependent upon the force acting on the object and the mass of the object
200
What is potential energy?
stored energy
200
what type of energy transformation is this?
You burn a piece of wood.
thermal to chemical
200
What is translucent light?
light scatters as it passes through the object
300
What is frequency and what unit is is measured in?
refers to how many waves are made per time interval
hertz
300
What is Newton's Third Law of Motion?
every action has an equal and opposite reaction
300
What ball has the highest potential energy?
the first one
300
What type of energy transformation is this?
The sun shines on the Earth.
Electromagnetic to thermal
300
What is opaque light?
light cannot pass through the object. it refracts or absorbs
400
When you change the frequency, what do you also change?
the wavelength
400
Example of Newton's Third Law
you run into your friend while in-line skating, and you both fall in opposite directions
400
What ball has the highest kinetic energy?
the third ball
400
What type of energy transformation is this?
You turn on a lamp.
mechanical to electrical
or
electrical to thermal
400
What are some examples of opaque light?
wood brick aluminium foil
mud oil lava
500
Draw and label the five parts of a transverse wave
500
Example of Newton's Second Law
You hit a baseball with a wooden and plastic bat. The baseball will go farther with the wooden bat.

Describe the particle arrangement in solids, liquid, and gases.
solids- really far apart and only a few
liquid- semi-close together and there are more
gases- really close together and there are a lot of them
