## What is the basic idea of the law of gravity as proposed by Newton?

Newton’s law of universal gravitation is usually stated as that every particle attracts every other particle in the universe 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.

## What is the law of gravity in simple terms?

a law stating that any two masses attract each other with a force equal to a constant (called the gravitational constant) multiplied by the product of the two masses and divided by the square of the distance between them.

**How does Newton’s law relate to gravity?**

Newton’s Law of Gravity says that gravity is a force that acts between any two objects with mass, and that force increases if the mass increases and decreases if the distance between the two objects increases. This is why objects fall to the ground and the moon doesn’t fly away from the earth.

**What are Newton’s ideas of gravity?**

Newton’s law of universal gravitation states that every mass attracts every other mass in the universe, and the gravitational force between two bodies is proportional to the product of their masses and inversely proportional to the square of the distance between them.

### How did Einstein explain gravity?

GETTING A GRIP ON GRAVITY Einstein’s general theory of relativity explains gravity as a distortion of space (or more precisely, spacetime) caused by the presence of matter or energy. A massive object generates a gravitational field by warping the geometry of the surrounding spacetime.

### What are the 3 laws of gravity?

In the first law, an object will not change its motion unless a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration. In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.

**How did gravity come into existence?**

The legend is that Newton discovered Gravity when he saw a falling apple while thinking about the forces of nature. Whatever really happened, Newton realized that some force must be acting on falling objects like apples because otherwise they would not start moving from rest.

**Is gravity a real force?**

Gravity is most accurately described by the general theory of relativity (proposed by Albert Einstein in 1915), which describes gravity not as a force, but as a consequence of masses moving along geodesic lines in a curved spacetime caused by the uneven distribution of mass.

#### How is gravity created?

The answer is gravity: an invisible force that pulls objects toward each other. So, the closer objects are to each other, the stronger their gravitational pull is. Earth’s gravity comes from all its mass. All its mass makes a combined gravitational pull on all the mass in your body.

#### What are Newton’s 3 Laws called?

What Are Newton’s Three Laws of Motion? The Newton’s three laws of motion are Law of Inertia, Law of Mass and Acceleration, and the Third Law of Motion.

**What is the first law of gravity?**

The Universal Law of Gravitation (Newton’s law of gravity): 1. Every mass attracts every other mass. 2. Attraction is directly proportional to the product of their masses.

**Where is gravity the strongest?**

In general, the closer the centers of two objects, the greater the force of gravity becomes. Therefore, you would expect gravity in the United States to be stronger wherever you are closest to the center of the Earth.

## How did Newton figure out the law of gravity?

Newton figured out the concept of gravity when an apple fell from a tree – he thought that there must have been some of the other forces that made an object like an apple move from rest.

## What does Newton say about the universal law of gravitation?

Newton ‘s law of universal gravitation states that every particle attracts every other particle in the universe with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

**What was the basic behind Newton’s law of gravity?**

The inverse square law proposed by Newton suggests that the force of gravity acting between any two objects is inversely proportional to the square of the separation distance between the object’s centers. Altering the separation distance (r) results in an alteration in the force of gravity acting between the objects.

**What was Newton’s secret about his theory of gravity?**

Newton publicized his Theory of Universal Gravitation in the 1680s. It basically set forth the idea that gravity was a predictable force that acts on all matter in the universe, and is a function of both mass and distance.
