What is a Wave? Water waves are just one of many kinds of waves.
What is a Medium? Is the material-solid, liquid, gas-trough which can travel.
What is a Transverse wave? The spring coils move up and down as the wave passes.
What is Crest in a wave? The points where the wave is highest.
What is Though in a wave? The points where the wave is lowest.
What is a Longitudinal wave? Particals move back and forth in the same direction that the waves travel.
What is Compression in spring coils? The coils being together.
What is Rarefaction in spring coils? The spread of the coils appart.
What is a Mechanical wave? Waves that require a medium.
What is a Electromagnetic wave? A wave with no medium.
What is Amplitude? Is a measure of how far partials in the medium move from their rest position.
What is Wavelength? Defined as the distance from any point on a wave to the next identical point on the same wave.
What is Frequency? Is the number of waves that pass a point in a given amount of time.
What is Hertz (Hz)? Is frequency measured.
What is Wave speed? Depends on properties of the medium.
What is Force? A push or a pull exerted on an object to change the motion of the object.
What is Work? The use of the force to move an object sum distance.
What is Power? The Ability to do something or act in a particular way, especially as a faculty or quality.
A book weighing 1.0 newton is lifted 2 meters. How much work was done? 2 Joules.
How much power is used if a force of 35 newtons is used to push a box a distance of 10 meters in 5 seconds? 17.5 watts.
what dose wave look like that gives a loud high pitched sound? Compression.
What dose a wave look like that gives a soft, low pitched sound? Low frequency.
What is the power of a kitchen blender if it can perform 30,000 joules of work in 15 seconds? 2000 watts.
How much power is used in a 500-watt microwave oven cooks for 5 minutes? 100 joules.
It took 500 newtons of force to push a car 4 meters. How much work was done? 2000 joules.
How much power is used in a 60-watt light bulb for 1 hour? 60 watts.
If there is a box 3 newtons and pushed it 100 meters. How much work did you use. 300 joules.
How would you represent compression and rarefaction? ;;;;;;; ; ; ; ; ;;;;;; ; ; ; ; ;;;;;;.
If you use the force of 100 newtons and have to move it 10 meters. With a power of 250. How much time did it take? 4 minutes.
