Understanding Gravitation
by Ron Kurtus (updated 16 March 2023)
Gravitation is the force of attraction between objects of matter—usually on a large scale. It is different than Gravity, which is an approximation of Gravitation and is the force that pulls objects toward the Earth.
Gravitation is a subject in Physics, which in turn is a branch of Physical Science. There is a great need for people who understand scientific principles and know how to think logically. Your knowledge and skills in these areas can help you excel in school, advance your career or improve your business.
The purpose of these free online lessons is to give you a start at improving your scientific knowledge of Gravitation that will help you become a champion in the field.
