key term - Newton’s Laws of Gravitation

Definition

Newton's Laws of Gravitation refer to the fundamental principles established by Sir Isaac Newton that describe the gravitational force acting between two masses. These laws provided a framework for understanding how objects interact with one another through gravity, laying the groundwork for advancements in mathematics, physics, and engineering during the period of technological innovations from 1450 to 1750.

5 Must Know Facts For Your Next Test

1. Isaac Newton published his work on gravitation in 'Philosophiæ Naturalis Principia Mathematica' in 1687, which fundamentally changed the understanding of motion and forces.
2. Newton's law of universal gravitation states that every mass attracts every other mass with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
3. The concept of gravity helped explain not only earthly phenomena but also celestial mechanics, such as the orbits of planets and moons.
4. Newton's ideas provided the foundation for future technological advancements, including those in navigation, engineering, and astronomy.
5. The application of Newton's laws led to improvements in shipbuilding and navigation techniques during this era, enabling longer sea voyages and greater exploration.
