work, power, waves

What is a wave? Vibrations in a medium.
What is medium? The material in which a wave can travel.
What is a transverse wave? When particles move perpendicular to the direction the wave is going.
What is crest? The point at which the wave is at its highest.
What is through? The point at which the wave is lowest.
What is a longitudinal wave? When particles move back and forth in the wave.
What is compression? When particles get closer in a wave while moving back and forth.
What is rarefaction? When waves get more spread out in a wave while moving back and forth.
What are mechanical waves? Waves that acquire a medium.
What are electromagnetic waves? Vibrations of electric and magnetic fields.
What is amplitude? A measure of how far particles move from there rest position.
What is wavelength? The distance from any point on a wave to the next identical point on the same wave.
What is frequency? The number of waves that pass a point in a certain number of time.
What is Hertz(Hz)? The measurement of frequency.
What is wave speed? The speed at which waves travel.
What is force? The push, pull, or exert on an object.
What is work? The force x the distance
What is power? The amount of distance of time
If a group of men apply a force of 700 Newtons to move a table 40 meters, what amount of work will they have to accomplish? 28000 Joules
A man weighing 500 Newtons gets on an elevator. The elevator lifts the person 5 meters in 6 seconds, how much power was used? 83.33 watts
What is the unit of Force? Newtons.
What is the unit for power? Watts.
What is the unit for work? Joules.
What is an example of Electromagnetic energy? Visible light, microwaves, ultra waves, x-rays, etc.
What does one Hertz(Hz) equal? 1 wave length per second.
What materials can waves travel through? Solid, Liquid, and Gas.
