Waves

work, power, and waves

QuestionAnswer
what is a wave A wave is a traveling disturbance that carries energy through space and or a medium without transferring matter
what is a medium A medium is the solid, liquid or gas through which a wave can travel
what is a transverse wave In a transverse wave particles moving perpendicularly compared to the direction of the waves
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 A longitudinal wave is a wave that moves back and forth in the same direction or parrael
what is compression compression is when something tightens it
what is a rarefaction A rarefaction is the expanded point of the wave
what is a wavelength A wavelength is the distance from any point
what is a mechanical wave A mechanical wave is a disturbance in a medium allowing the energy of the wave to travel
What is a electromagnetic wave Is a disturbance that carries energy through a space or medium
what is amplitude Amplitude is the measure of how far away particles
what is frequency the number of waves that pass a point
What is hertz Hertz is the frequency of a wave
What is power Power is the rate at which work is done
what is wave speed wave speed is the speed of the wave
what is work work is how much power is being used work=force. distance
A person weighing 700 N gets into a car the car drives 10 me in 10 seconds how much power was used P=700 watts
A set of trains drag a 900 N crate 5 meters in 8 seconds what power was used P=642.85 watts
If 58 watts of power is produced in 16 seconds how much work is done P=928 J
If 58 joules was necessary to move a 6 N crate how far was the crate moved d=9.6 Meters
If 400 J was needed to a box a distance of 10 meters what is the weight of the box F= 40 N
If 75 J is necessary to move a 10 N fridge how far was the fridge moved d= 7.5 M
what can waves use as mediums solid,liquid and gas
what is force force is the power of work on an object
