# Waves, Work & Power

### Study stack for Waves, Work & Power

_____ are caused by vibrations of a medium. Waves
_____ is the material that a wave can travel through. A Medium
______ are the tops of a transverse wave. Crests
______ are the very bottoms of a transverse wave. Troughs
______ the starting point of the wave. Restingpoint
In a ________, the particles move perpendicularly compared to the wave. Transverse Wave
A ________ has the particles move back and forth, just like the wave. Longitudinal Wave
_______ are the part of a longitudinal wave that are closer together. Compressions
_______ are where the particles are more spread out in a longitudinal wave. Rarefactions
______ is an activity involving a force and movement in the direction of the force. Work
_____ is the rate of doing work or the rate of using energy. Power
_____ is the number of waves that pass through a point at any time. Frequency
_____ is the distance between any similar point in a wave. Wavelength
The _______ is a measure of how far particles in the medium move from their resting point. Amplitude
_____ is the capacity of doing work Energy
A__________ is a wave that needs a medium to travel through Mechanical Wave
A__________ is a wave that does not need a medium to travel through Electromagnetic Wave
The unit that measures frequency Hertz
A 60 N girl pushed a cart 10 meters, what is the amount of work? 600 Joules
If you do 25 Joules of work in 5 seconds, how much power did you generate? 5 Watts
The speed of the wave was 5 cm/s and the wave traveled 45 cm. How long did it take for the wave to travel? 9 Seconds
A boy did 400 Joules of work and generated 80 Watts, how long did it take him? 5 Seconds
A waves travels for 4 Seconds and the speed was 40 cm/s, how far did the wave travel? 160 Centimeters
If you carry a box for 12 meters and generated 144 Joules, how many newtons did the force have? 12 Newtons
A boy generated 250 Joules of work, so how much energy did he expend? 250 Joules of Energy
