## Where does force of gravity end?

The Earth’s gravitational field extends well into space it does not stop. However, it does weaken as one gets further from the center of the Earth. The Shuttle orbits about 125 mi above the surface, roughly the distance between Jackson and Nashville!

## What happens to the gravitational force?

So as the mass of either object increases, the force of gravitational attraction between them also increases. If the mass of one of the objects is doubled, then the force of gravity between them is doubled. If the mass of one of the objects is tripled, then the force of gravity between them is tripled.

**What happens to the gravitational force at the Centre of the earth?**

If you are at the center of the earth, gravity is zero because all the mass around you is pulling “up” (every direction there is up!).

**How is gravitational force related to the mass of an object?**

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.

### Does gravity decrease towards the center of the earth?

As you move towards the center, there is less and less of the Earth closer to the center than you are, so the gravitational field gets weaker and your weight decreases. At the exact center of the Earth, the gravitational field is actually zero.

### Where does the gravitational pull get its energy?

So gravity does its job and it pulls each other closer, this gets turned into kinetic energy. This is where I’m lost. According to the law of conservation energy can’t be created or destroyed and the kinetic energy comes from the gravitational pull so where does the gravitational pull gets its energy.

**What is the gravitational force called?**

Lesson Summary. The gravitational force is a force that attracts any objects with mass. You, right now, are pulling on every other object in the entire universe! This is called Newton’s Universal Law of Gravitation.

**What is the universal force of gravity?**

Universal Gravitation Equation. This equation describes the force between any two objects in the universe: In the equation: F is the force of gravity (measured in Newtons, N) G is the gravitational constant of the universe and is always the same number. M is the mass of one object (measured in kilograms, kg)

#### Why is the gravitational force attractive?

We call the gravitational force attractive because it always tries to pull masses together, it never pushes them apart. In fact, every object, including you, is pulling on every other object in the entire universe! This is called Newton’s Universal Law of Gravitation.
