Gravitational Fields
This unit examines gravitational fields and their role in shaping planetary motion, satellites, and the structure of the cosmos. Learn what a gravitational field is, how it varies with distance, how Newton’s law of universal gravitation describes the force between masses, and how these ideas explain orbits, potential energy, and satellite motion.

The Elusive Power
of Gravity
There are (currently) four fundamental forces in the universe: electromagnetic, strong and weak nuclear, and finally gravitational.
The holy grail for many scientists, Einstein included, was to develop a grand unified theory that could explain all of these, but gravity has proved to be the most elusive – why?
It is 10^40 times weaker than the electromagnetic force, yet it has shaped and moulded the structure of the universe. The moon’s gravity can lift entire oceans from 400,000 km away, yet you can overcome the gravitational force of the Earth every time you walk upstairs.
Unlock the Mysteries of Gravity
Gravitational fields link fundamental physics to real‑world applications, from satellite mechanics to planetary motion. With tailored lessons, you’ll build confidence, tackle exam questions, and connect physics principles to the universe around you.
