QuestionAnswer
What is a Wave? The vibration in a medium.
What is a Medium? The material-solid, Liquid or gas through witch a wave can travel.
What is a Transverse wave? When the particles move perpendicularly to the direction to the wave travels.
What is the Crest? The highest points of a transverse wave.
What is the Trough? The lowest points of a transverse wave.
What is a Longitudinal wave? Particles that move back and forth in the same direction that the waves travels.
What is Compression? The part where the particles bunch together.
What is a Rarefaction? The spreading of the particles to be spring loaded .
What is a Mechanical wave? The waves that require a medium.
What is a Electromagnetic wave? The waves that are not a disturbance in a physical medium.
What is Amplitude? 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 on the same wave.
What is Frequency? The number of waves that pass a point in a given amount of time, usually one second.
What is Hertz? The measure of Frequency.
What is Wave speed? The speed that the wave travels.
What is Force ? The push or a pull exerted on an object in Newtons.
What is Work ? The use of force to move an object some distance.
What is Power? Is how much work you do in a amount of time.
If 120 W of power is produced in 37 seconds, how much work is done? 4,440 J
If you move a 35 N bad of apples and move it 70 meters how much work is done? 2,450 J
What is the difference between mechanical waves and electromagnetic waves? Mechanical waves require a medium and electromagnetic waves are not a disturbance in a physical medium.
What is the difference between longitudinal waves and transverse waves? Longitudinal waves the particles move in the same direction that the waves travel and transverse waves the particles move perpendicularity to the direction of the wave travels.
What usually comes after a compression in a slinky? A rarefaction.
Do you do work if you go anywhere? you do not because you need to move to do work.
If you weight more then do you do more power? yes because you do more work, resulting in more power.
Would you do more work if you went fast up the stairs or slow? you would do the same either way.
