They are identical.
GRAVITY... 2nd answer: The force that pulls all objects toward each other is gravity. The earth exerts the force of gravity on you, and you exert the force of gravity on the earth ( or your couch, dog, etc). We notice Earth's force of gravity because it is huge compared with the force of gravity of our bodies .... or the force of gravity of our bowling balls, and so forth.
Gravitation is the only force that acts universally.
The force of attraction between masses is called gravitional force or gravity
The force that pushes downward on objects on earth is called gravity.
Gravity
Sorry. They can't, because gravity is real and centrifugal force isn't.
All bodies with mass are attracted to the Earth by gravity, so when a body is raised you must do work to raise it. This work is equal to force x height, if force is in Newtons and height in meters, the work is in units of Joules.
It does. Gravity works on all matter
The force that is at work is gravity. If you are thinking of bouyancy, it is not a force.

Work is being done by the force of gravity. When the book falls to the floor, there's a force on it, and the force keeps acting on it as it covers the distance. A force acting through a distance is the definition of work. Maybe there's nobody pushing the book, but the force of gravity is pulling it down, and it's the force of gravity that does the work on the book.
Work Done = Force x Distance = Power / Time = (Force x speed)/Time
Gravity is the only real force at work here, The mass affects the gravity, but the gravity is the only one that could be termed a "force".
Work is definied in Physics as the Force acting on an object times the distance the object is moved by that Force, or W = fd Since Force is mass times acceleration (F=ma), and because the ball is on a surface that is perpendicular to the force exerted by gravity, there is no gravitational acceleration (a), hence no Force, so no Work is done by gravity.
Gravity and elastic force...
it works by reacting to the force created by the mass of your body being in a gravitational field. in short it works by using a force. but that force is because of gravity.
