Newton's law of gravitation
The force between two point masses is directly proportional to the product of the masses and inversely proportional to the square of the separation between them
gravitational field strength
The force per unit mass experienced by a small test mass placed in the field
Work done per unit mass in bringing a test mass from infinity to that point in the field
gravitational potential energy
Work done in moving a mass from infinity to that point in the field
A surface on which the potential is the same everywhere and no work is done when moving across it
Kepler's third law
The square of the orbital period of a planet is directly proportional to the cube of the semi-major axis (radius) of its orbit.
The minimum velocity for a ballistic projectile to escape a planet's gravitational field
An orbit in which a satellite orbits in the same direction as the Earth's rotation, above the Earth's equator and with a period of 24 hours, thus allowing it to maintain a constant position over the Earth's surface
