i have to do an assesment about sound. i have to include the big idea of energy. i have no clue what it is! HHEELLPP MMEE!!

What do you mean when you say "the big idea of energy"?

I know that sound is created by vibrations, but I'm not sure that's exactly what you are looking for.

i have no clue of what the big idea of energy is please plese help me becouse i have to do an asessment on the iron and silpher reaction and it askes me to explain what the big idea of energy is.

LOL, your teacher must be using the same stupid text book as mine. It's always going on about the big idea of energy and I have no clue what it is either, and I'm just doing the Iron and Sulpher homework too. Did you get the even more stupid homework on the EAr defenders. AGGHHHHHHHHHH!

The total off energy and matter in the universe is constant, but that energy and matter are equivalent and can be interchanged-

And how i translated that from geekspeak was that energy and matter are kinda like twins that change place, and that everything in the universe is constant and on going-if that didn't help much i totally understand-i didn't understand it for the first 3 years.

this makes no sense....i got a whole sheet on this and i don't get any of it someone plz help me out!!!

Energy can't be made or destroyed, just changed from one type to another. When something burns, you aren't making energy, just changing it from chemical (stored in the wood) to heat and light (the flame).

Hope this answers your question, but you are right. Those sheets really suck.

WOW thanks this helps a lot :) i just don't get how you figured this out... lol
