Interference

Construtive inteference is when two or more waves go together and they combine a whole wave, a deconstructive wave is when two waves meet and they and both crests line up together.

Deconstructive: when two cars get into a car crash... They both line up they do not end up on a v shape.. They crash in a vertical line. Which means two forces going together leading into one "line"

Constructive: when two ocean waves go together and they crash making another huge wave showing it is constupructive wave,

Standing Waves

Today in class we were using slinks, we used the slinkys to measure the frequency of the waves.

I learned that the more force you exorted to the slinky, the further thw wave would be from you and the wave would come back stronger than it had began..also that the wave length and frequency are alike because the lentgh is created by the amount of frequent moves you are going tonbe able to make

No effect

Something i think that should effect something would be going on a swing while on a sunny day.. You would think that while going back and forward with all your body power that the wind would set you off but it wouldn't because the wind is a weaker force compared to what is pushing the swing, i thought it would effect the swings speed or motion but it doesn't

Simple harmonic motion

What is simple harmonic motion? It is a weight hung so that it swings freely back and forth

Three good examples of simple harmoic motion is a swing , a washer on a string and lastly a spring

       Swing: it goes back and forth freely when the person moves their legs back and forth the potential energy the person puts in is what makes it move freely back and forth

          A washer on a strong: the washer applies weight on the string , the string gets its speed from when you let go of the washer.. It moves side to side without stopping.

              Spring: the spring has weight in it already it moves up and down , when it is getting pulled downward its the energy that it will have to go back up and back down, which means its a harmoic motion

Electricity Generator

The Generator im most interested in is the solar power panel. 

I choose it because it is the most easy to use , its cheap , an you wouldn't pay for all the electricty you would be using.. You would only pay for the panels you would need in order to work. How does the solar power panel work? It's panel is amde up of circuits.. Which then transfer into a wire down to house which then become electircity for your appliances at home.

Something that is bad about this generator? If the sun were ever to go out...we  wouldn't have any more electricity to run around the house
