What we call "gravity" is a fact of nature that causes forces of attraction in both
directions between every two specks of mass, no matter where they are or what
else is in between them. The forces are stronger if the masses have more mass,
and if they're closer together.
That's the connection between gravity and the force of it.
(The force of gravity is not the only force there is. Force can also be generated
by a muscle in your arm, an electrical charge on a rubber balloon, a bottle rocket,
a horse, wind, a gasoline engine, flowing water, a stretched rubber band, etc.)
Gravity. Well, the strong nuclear force and the electromagnetic force can pull matter together, but electrical and magnetic forces can also repel. Gravity always attracts. This particular question is pretty obviously about gravity.
In both directions along the line between the centers of the two masses that are being drawn together by gravity.
No, the force of gravity does not do work on a satellite when it is in motion because the direction of the force is perpendicular to the direction of motion.
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.
Gravity is the force that causes all matter to be attracted together. It is a fundamental force that causes objects with mass to exert an attractive force on each other.

Gravity, the force of attraction between all masses in the universe, is the inward force that holds a star together.

Gravitational force (or gravity) is a force that pulls things together.
The answer is simple: gravity.
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.
Gravity is the force that causes all matter to be attracted together. It is a fundamental force that causes objects with mass to exert an attractive force on each other.
Yes, a nebula is held together by gravity. Gravity causes the gas and dust within a nebula to contract and clump together, eventually forming stars and other celestial bodies.
