Waves
work, power, and waves
| Question | Answer |
|---|---|
| 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 |
