Does the earth fall around the sun

Part of the theory behind floating objects in space is because "technically speaking" these objects are in a constant free fall around the earth (gravitational attraction). Using this theory, could it be said that the earth it's self is in free fall around the sun ?

I think this is a word issue. "Fall" implies that gravity is pulling something toward the center of the earth. If the earth was constantly falling toward the sun, it would have burned by now. Instead of falling, it is orbiting. As it moves, it's course is constantly being altered by gravity to a near circular orbit. It is the combination of the gravitational force and the velocity of the earth's movement combined that cause it to orbit. If it was standing still, the gravity would cause it to "fall" into the sun but the added velocity of the movement creates the orbit.

The question that is most difficult to answer is what is the source of energy that causes the planets motion around the sun rather than falling into it. Are we still riding on the momentum gained from a "big bang" or are there other forces?
