Stack #2744182

What is a wave? A vibration in a medium.
What is a Medium? Is the material for which a wave can be created. A solid, liquid, gas.
What is a Transverse Wave? A wave where the particles move perpendicularly to the direction the wave travels.
Where is the Crest? The highest points on a wave.
Where is the Trough? The lowest points on a wave.
What direction does a Longitudinal Wave move? Parallel to the direction of where the wave travels.
What does Compression mean on a slinky? When the coils come together.
What does Rarefaction mean on a slinky? When the coil spread apart.
What does a Mechanical wave need? A Medium.
What does an Electromagnetic wave need? Not a medium, but a electric and magnetic field.
What's Amplitude? The increase/decrease between the crest/trough to their rest position.
What's the Wavelength? The distance between crest to crest or trough to trough.
What's Frequency? The number of waves in a select amount of time.
What's the Wave Speed? The speed the waves travel in.
What's Force? The push or pull applied on an object.
What's Work? The force to move an object a distance.
What's Power? The time it takes to do work.
What's Hertz? The measurement of frequency.
Where is the rest position on a wave? In the middle of the crest and trough.
How do yo calculate work? Distance times force
How do you calculate power? Work/ time
Work is measured in ___________. Joules (J)
Power is measured in ___________. Watts (W)
Force is Measured in ____________. Newtons (N)
If Jasmine used a force of twenty-two newtons to move a cat ten meters, how much work did she do to move the cat? 220 J
If it took Jasmine the work of 500 J to move the chair in 10 seconds, how much power did she use? 50 W
If Damian put 1440 J of work into moving the crate 32 feet, what force was used? 45 N
Florence used 25 watts of power in 12 second, what was her work? 300 J
If Sam used 12 J in 10 seconds to move the box, how much power did she use? If she moved the same box with the same amount of work the distance of fifteen meters, how much force was need to move the box? 1.2 W and 0.8 N
If a boat was floating and you started a stopwatch when one crest passed and stopped it when the fourth crest passed and it took sixteen seconds passed, what was the frequency from each wavelength? 4 seconds for each wavelenghth
If one wavelength between two crests is 0.1 inches, what would be the wavelength between 4 crests? 0.3 inches
If particles are moving the same direction of the wave it is a ___________ wave and if particles are moving perpendicular to the wave it's a ______________ wave. Longitudinal, transverse
True or False: 40 J times 20 seconds equals 800 watts. Explain why it's true or false. False: the formula for power is P=work/time and not P=wt.
What's the difference between the crest and the trough. The crest is the tallest points on a wave and the trough is the lowest point.
On a longitudinal wave how do you increases the amplitude? You increase the force you put on it.
