"TurtleMeister wondered what would happen if the composition of the masses had some influence in how objects accelerate due to gravity" Why use "accelerate" and "gravity" as if they are different concepts?

Question from an uneducated inquisitive soul, your post seem to acknowledge a difference between acceleration and gravity. Doesn't Einstein prove that acceleration and gravity to be the same thing?

The difference between the human mind and random selection is our ability to apply reasoning to information gathering and shorten the amount of time it takes to arrive at the truth.

Because there is only one absolute correct answer vs. many, many incorrect answers. We learn what is not and keep narrowing the possibilities.

Temperature - a measure of the average kinetic energy of the particles in a sample of matter, expressed in terms of units or degrees designated on a standard scale. Notice the defination uses the word temerature as a measure of kinetic energy? Now I resent having the word stupid use as...

Why all the fuss. In a vacumn all objects fall at the same rate. If there is an atmosphere it will offer resistance to the object falling just as the planets surface will continously halt the object from falling. If the planet changes in size the object adjust with it.

If there is conservation of energy there is no final state only constant states of change. In the case you mentioned the available energy from the coal is depleted by moving objects and changing temperaturers.

All materials to give off heat as energy must be converted to a gaseous state. Ask any fireman. Solid, to a liguid, to gaseous, to combustion. now using this energy build-up thru heat utilizing this to do work, weather moving a train trhu mechnacial energy or moving leaves thru creating pressure...

This is false. No matter what the mass, all objects accelerate at the rate of 32 ft. per second squared in a vacumn. Note. If there are only two objects in the entire universe, our sun a me both objects move towards each other. With no other reference there is no reference point. They just...

Sweep all the clutter :) aside and your left with combustion is the act of a substance (ex. coal) changing to a liquid, then changing to a gas and ignited (as the temperature increases) which then causes air molecule movement to increase and expand increasing pressure. Depending how rapid this...
