Define Gravitational force,Electrostatic force and Magnetic force?
Gravitational Force is the force of attraction between all masses in the universe. Its not a force of contact, but its that pull of that object back towards the earth, like the waves, or when one shoots a basketball, the force of gravity acts to pull the ball back to the floor.
Electrostatic Force is the phenomena arising from stationary or slow-moving electric charges. Its like the attraction of the plastic wrap to your hand after you remove it from a package.
Magnetic Force is the force that exists between two electrically charged moving particles. An example is like when you place a small magnet under a piece of paper and sprinkle iron filings on it and the filings are drawn to that magnet.
Gravitation, or gravity, a natural phenomenon in which objects with mass attract one another. One of the mysteries of the atom is that the electron and the nucleus attract each other. This attraction is called electrostatic force, the force that holds the electron in orbit. The electric field is defined as the force per unit charge that would be experienced by a stationary point charge at a given location in the field. The force exerted between magnetic poles, producing magnetization.

Why is there more gravitational pull on earth than on other planets?Are other planets really habitable?

Having a wondering about it moment. I don't have an answer. That black hole at the center of our universe may not exert its pull upon the earth as much as it does on our sun. ...

...there would be no gravity.My reasoning comes from the Shell Theorem:http://en.wikipedia.org/wiki/Shell_theoremSimply put, a spherical shell exerts no net gravitational force on objects inside it. Likewise, there will...

What is the “speed” of gravity?Hypothetically, if one remove the Sun from its place, when the Earth would be affected? Momentary, by the speed of light or by some speed specific to the gravity...?
