The Law of Universal Gravitation Explained
In this video, you will definitively understand Isaac Newton's Law of Universal Gravitation and how it influences the world around us. Discover the real difference between weight and mass and how physics affects the numbers that appear on the scale.
The Law of Universal Gravitation explains the force of attraction between bodies, based purely on their masses and the distance that separates them. We detail the famous physical formula, clarifying important variables such as the gravitational constant and why distance is measured using the radius squared.
In addition to dissecting the first-degree equation behind the theory, we explore how the attraction of the Earth and even the Moon works in practice. You will understand why being at a high altitude slightly decreases the force of weight, proving that mass and acceleration due to gravity are completely different concepts.
