do you belive there are only two types of energy, kinetic and potential or do you belive that each are different as some listed below

Chemical
Elastic
Gravitational
Nuclear
Heat
Kinetic
Electrical
Electro-magnetic

what do you mean? Most of those listed are types of potential energy. How is this a matter of belief?

I'm afraid you don't quite understand what potential energy is. I suggest you read the definition in any good dictionary and look it up on Wikipedia.

i only listed a few but what i mean is that some people belive there are onbly two types of energy potential and kenetic and then they each have types of energy under each where as some people belive that the long list is seperate and does not fall under being kenetic or potential

"Some people believe", those would be the ones that don't particularly know much then?

Very well. If you think you understand the precise definitions of potential and kinetic energy, then take your short list and tell us just ONE there that doesn't fall under the two categories.

there isnt thats the point but according to my science teacher each is different and falls under neither kinetic or potential and then he started talking crap i didnt understand about something quad something

Does anyoneelse find issue with the statement of the question?

Energy is energy man.

If you didn't understand (which is pretty obvious, I guess) ;) then you should be making MORE effort to understand and even do a little studying outside class. Believe me, it won't hurt you at all.

Couldn't kinetic energy, be construed as potential energy, providing there is no friction or impact. It seems that kinetic only means that is moving, but that moving object has potential energy doesn't it.

Are You Sure ?

Yep. It all comes down to the same equation:

E^2 = m^2c^4 + p^2c^2

There's only one type of energy. It just gets stored in different places.

Need to add mechanical energy to the list!
