What is Force? A push or pull exerted on an object.
What is Work? The use of force to an object some distance.
What is a wave? A disturbance that transfers energy.
What is a medium? The material (solid, liquid or gas) through which a wave can travel.
What is a crest? The point where the wave is the highest.
What is a trough? The point where the wave is the lowest.
What is a Longitudinal Wave? Wave particles move back and forth in the same direction that the wave travels.
What is Compression? The effect, result, or consequence of being pushed together. The opposite of rarefaction.
What is Rarefaction? The reduction of an item's density. The opposition of compression.
What is a Transverse Wave? Wave particles move up and down as the wave passes.
What are Mechanical Waves? Mechanical Waves are waves which move through a material medium (solid, liquid, or gas) at a speed that depends on the type of medium. Examples of mechanical waves are longitudinal and transverse.
What are Electromagnetic Waves? Electromagnetic waves are waves that require no medium and could travel through outer space.
What is Amplitude? Is a measure of how far particles in the medium move from their rest position.
What is Wavelength? The distance from any point on a wave to the next identical point. Ex. A crest to the next crest.
What is Frequency? Is the number of waves that passes a point in a given amount of time.
What is Hertz (Hz) One hertz is equal to one wavelength per second.
What is Wave Speed? The speed that waves travel. Equation. Wave Speed = Wavelength/ wave period.
If 5 kg were moved vertically 1 meter in 3 seconds, what would the power generated be? (5kg x 1 meter) / 3 seconds = 1.66 kg-meter per second
If 3 kg were moved vertically 2 meters, what would work be? 6 kg-meters of work.
If a wave has a wave speed of 10 m/s and it took 5s to pass by, what would be the wavelength? the wavelength is 2m
If you measure two crests on a wave, what is term that defines the measurement? That measurement would be the wavelength.
If a sound wave has a wavelength of 20m and the frequency of the wavelength is 5, what is the wave speed? The wave speed would be 100 m/s.
Which of the following would be able to travel into deep outer space without a medium, a Mechanical wave or an Electromagnetic wave? An electromagnetic wave.
If a sound wave is transmitting through a cement wall or a trampoline, which of those two would transmit a slower wave? The more flexible a medium is, the slower it transmits waves. Therefore the trampoline would transmit the slower wave.
Which of the following terms defines when a slinky is tight together rather than spread apart? Rarefaction, Compression, Amplitude? Compression would show how the waves are compressed together and tight.
What is power? The rate at which work is done. P=W/t
