Work, Power, Waves
work power waves.
Question | Answer |
---|---|
force | push or pull exerted on an object in order to change the motion of the object |
work | the use of force used to move an object some distance |
power | how fast you can accomplish work |
wave | waves are caused by vibrations of a medium |
medium | the material which a wave travels through |
crest | the highest point of a wave |
trough | the lowest point of a wave |
longitudinal wave | particles move back and forth in the same direction that the wave travels |
compression | when coils are pushed closer together |
rarefaction | when coils are pulled apart |
transverse waves | particles moving perpendicular |
mechanical waves | a wave that requires a medium |
electromagnetic waves | a wave that doesn't require a medium |
amplitude | a measure of how far particles in the medium move from the rest point |
wavelength | the distance between crests and troughs |
frequency | the number of waves that pass a point in a given amount of time |
hertz | how frequency is measured |
wave speed | the speed a wave travels |
if a dog weighs 300 newtons and you carry it 60 meters how much work do u use | 18,000j |
if you use 1200j in 15 minutes what is the power | 0.0125w |
if the wavelength is 10 and the period is 2 minutes what is the wave speed | 0.2 |
what is work measured in | joules |
what is power measured in | watts |
what is frequency measured in | hertz |
what is the formula to find work | force times distance |
what is the formula to find force | work devised by distance |
