Newton's law of gravitation

In summary, Newton's law of gravitation is a fundamental physical law that states that every object in the universe attracts every other object with a force directly proportional to their masses and inversely proportional to the square of the distance between them. It explains the force of gravity that holds planets in orbit, keeps objects on Earth from floating away, and serves as the foundation for understanding other principles like the movement of celestial bodies and tides. Isaac Newton developed this law through his observations and mathematical understanding, and it applies everywhere in the universe. There is significant evidence supporting this law, including accurate predictions of planetary orbits and other phenomena, as well as confirmation and expansion from later scientific discoveries like Einstein's theory of general relativity.

When a falling meteor is at a distance above the earth’s surface of 3.61 times the Earth's radius, what is the acceleration of the Earth's gravity in m/s2? (Use the average radius of the Earth in your calculations)


can somebody walk me through this one? thanks

What is Newton's law of gravitation?

Newton's law of gravitation is a physical law that states that every object in the universe attracts every other object with a force directly proportional to their masses and inversely proportional to the square of the distance between them.

What is the significance of Newton's law of gravitation?

Newton's law of gravitation is significant because it explains the force of gravity that holds the planets in orbit around the sun and keeps objects on Earth from floating away. It also serves as the foundation for understanding other principles, such as the movement of celestial bodies and the tides.

How did Newton come up with this law?

Isaac Newton developed his law of gravitation through his observations of falling objects and the motion of the planets. He combined these observations with his mathematical understanding of calculus to derive the law.

Does this law apply everywhere in the universe?

Yes, Newton's law of gravitation applies everywhere in the universe. It is a fundamental law of physics that governs the behavior of all objects with mass.

Is there any evidence to support Newton's law of gravitation?

Yes, there is a significant amount of evidence supporting Newton's law of gravitation. This includes the accurate predictions of planetary orbits, the behavior of objects in free fall, and the tides, among other phenomena. Additionally, later scientific discoveries, such as Einstein's theory of general relativity, have also confirmed and expanded upon the principles of Newton's law of gravitation.
