The video tutorial explains gravitational force as the attraction between objects in the universe, focusing on Earth's gravitational influence on nearby bodies like the moon. It highlights that every object exerts a gravitational pull, with the Sun's massive gravitational force maintaining planetary orbits. Newton's law of universal gravitation is discussed, detailing how gravitational force is proportional to the product of two masses and inversely proportional to the square of their distance. The video concludes with a thought experiment on the effects of halving Earth's gravitational force.
