## What is universal law of gravitation answer?

What is the Universal Law of Gravitation? Newton’s Law of Universal Gravitation states that every particle attracts every other particle in the universe with force directly proportional to the product of the masses and inversely proportional to the square of the distance between them.

## How the force between the two bodies is affected if the distance between them is tripled?

If the separation distance between any two objects is tripled (increased by a factor of 3), then the force of gravitational attraction is decreased by a factor of 9 (3 raised to the second power).

## What happens to the gravitational force between two objects as they move farther apart?

Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces. So as two objects are separated from each other, the force of gravitational attraction between them also decreases.

## 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.

## What does G and G stand for?

Relationship Between G and g g is the acceleration due to the gravity measured in m/s2. G is the universal gravitational constant measured in Nm2/kg2. R is the radius of the massive body measured in km. M is the mass of the massive body measured in Kg.

## Which two changes would increase the gravitational force between two objects?

The ways to increase the gravitational force between two objects would be by: Increasing the mass of one of the objects or increasing both their masses. Decreasing the distance between the two bodies by bringing the two objects together.

## What happens to force when distance is doubled?

Answer: a) When the distance between the two objects is doubled, the gravitational force becomes one-fourth.

## Why is G called the universal gravitational constant?

Universal gravitational constant, G is independent of the nature of the particle, medium between the particles, and time. Its value is constant anywhere in the Universe, and hence it’s called ‘Universal’.

## Which object most likely exerts the strongest gravitational pull on other objects?

One of Sir Isaac Newton’s accomplishments established that the gravitational force between two bodies is proportional to their masses. All other things being equal, the planet with the strongest pull is the one with the largest mass, which is Jupiter.

## What are 2 factors that affect the force of gravity?

When dealing with the force of gravity between two objects, there are only two things that are important – mass, and distance. The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them.

## Which planet has the strongest gravitational force?

Jupiter has the highest amount of gravity in our solar system. Jupiter is the largest in our Solar System, meaning it also has the highest gravity. You would weigh two and a half times on Jupiter than what you would on Earth.

## Which body exerts the weakest gravitational force on Earth?

The Moon is much, much smaller, but relatively close, so it also exerts a considerable gravitational force (and vice versa). So the body with the weakest gravitational influence should be far away and/or have a small mass (as compared to Earth).

## Does gravity increase or decrease with greater distance?

Gravity is affected by the size of objects and the distance between objects. A measure of the amount of matter in an object is mass. An object with a greater mass falls faster than an object with a smaller mass. When the distance between two objects increases, the force of gravity decreases.

## What happens to force if distance is halved?

Answer : When the distance is halved, force of attraction becomes four times.

## What is the unit of force?

The SI unit of force is the newton, symbol N. The base units relevant to force are: The metre, unit of length — symbol m. The kilogram, unit of mass — symbol kg. The second, unit of time — symbol s.

## What is Newton’s 2nd law called?

The other name for Newton’s second law is the law of force and acceleration.

## What’s Newton’s 4th law?

Any object has a tendency to stay in its current state. This tendency is called inertia. Any object has a tendency to stay in its current state.

## What is gravity caused by?

Earth’s gravity comes from all its mass. All its mass makes a combined gravitational pull on all the mass in your body.

## Is value of g constant?

The value of G is (6.6743 ± 0.00015) × 10−11 m3 kg−1 s−2. It must be pointed out that G occupies a rather anomalous position among the other constants of physics.

## Is small g constant?

This variation is very slight, the value of g varies from approximately 9.78 9.8 m/s2 at the Equator to approximately 9.83 9.8 m/s2 at the poles. On the other hand, the value of G is considered to be constant at all locations in the universe.

## Between which pair of objects is gravitational pull the strongest?

Objects that are closer together have a stronger force of gravity between them. For example, the moon is closer to Earth than it is to the more massive sun, so the force of gravity is greater between the moon and Earth than between the moon and the sun. That’s why the moon circles around Earth rather than the sun.

## Does gravity depend on mass?

The magnitude of this force depends upon the mass of each object and the distance between the centers of the two objects. Mathematically, we say the force of gravity depends directly upon the masses of the objects and inversely upon the distance between the objects squared.

## How does mass affect gravity?

Gravitational force is an attraction between masses. The greater the size of the masses, the greater the size of the gravitational force (also called the gravity force). The gravitational force weakens rapidly with increasing distance between masses.

How are g and G related? Answer: The universal gravitational constant (G) and the acceleration due to gravity (g) are directly proportional to each other.
