My favorite is One Stop English. They have lots of lesson plans, teaching ideas, grammar information and more.
Can anyone send me some useful sites for English language teachers?

The previous answer described gravity in the Newtonian sense, but Einstein had a very different explanation. He said that massive objects cause space to warp (like placing a bowling ball on a trampoline). Massive objects are "attracted" to other massive objects because they fall into these gravity wells. Thus, there is no energy conversion, only a tendancy for objects to follow the path of least resistance through space (as when you place a marble on the edge of the trampoline and it "falls" inward toward the bowling ball).

How much mass is Earth converting to energy per unit time to generate its gravity?
