Key Concepts

Kepler's Third Law

Kepler's Third Law establishes that the square of the orbital period of a body is proportional to the cube of the semi-major axis of its orbit. This principle links the time it takes to orbit with the size of the orbit and is a cornerstone of orbital mechanics.

Newton's Law of Universal Gravitation

This law explains that every two masses in the universe attract each other with a force that is proportional to the product of their masses and inversely proportional to the square of the distance between them. It is fundamental for understanding the forces that govern orbital motion.

Centripetal Force

Centripetal force is the inward force required to keep an object moving in a circular path. In orbital mechanics, this force is supplied by the gravitational pull of the central body, maintaining the object's orbit.

Orbital Period

The orbital period is the duration it takes for an orbiting object to complete one full revolution around a central body. This concept is essential for determining the timing and synchronization of satellite movements.

Orbital Speed

Orbital speed is the constant velocity an object must have to stay in a stable orbit. It results from the balance between gravitational pull and the object's inertia, and it plays a key role in maintaining a circular orbit by providing the necessary centripetal acceleration.
