Key Concepts

Newton's Law of Universal Gravitation

This fundamental law explains how every mass exerts an attractive force on every other mass. It quantifies the gravitational attraction between the satellite and the planet, which is essential for calculating the satellite's orbital speed and radius.

Orbital Mechanics

This area of physics studies the motion of objects in orbit and involves understanding how velocity, altitude, and gravitational forces interact. It provides the framework for predicting and maintaining stable orbits, ensuring that the satellite remains in a continuous free-fall around a planet.

Gravitational Force

This is the force that attracts two masses toward each other. In the context of satellites, gravity from a planet provides the necessary pull to keep the satellite in orbit, counteracting the satellite’s tendency to move in a straight line due to inertia.

Inertia and Centripetal Motion

The principle of orbiting involves a balance between the satellite's inertia, which tends to move it in a straight line, and the gravitational pull acting as a centripetal force that constantly redirects it, resulting in a curved, often circular, path around the planet.
