## Does gravity change depending on where you are?

Gravity is often assumed to be the same everywhere on Earth, but it varies because the planet is not perfectly spherical or uniformly dense. It’s also weaker at higher altitudes, further from Earth’s centre, such as at the summit of Mount Everest.

## Do we really know what gravity is?

We don’t really know. We can define what it is as a field of influence, because we know how it operates in the universe. And some scientists think that it is made up of particles called gravitons which travel at the speed of light.

## How does gravity keep you on the ground?

In statement form: Every mass attracts every other mass through the force called gravity. The strength of the gravitational force attracting any two objects is directly proportional to the product of their masses. For example, doubling the mass of one object doubles the force of gravity between the two objects.

## Where does gravity pull everything towards?

On Earth, gravity pulls all objects “downward” toward the center of the planet. According to Sir Isaac Newton’s Universal Law of Gravitation, the gravitational attraction between two bodies is stronger when the masses of the objects are greater and closer together.

## Where is gravity strongest on earth?

The effect of Earth’s gravity is stronger, the closer you are to the centre of gravity, roughly the centre of the earth. So the gravitational effect will be slightly weaker at the equator than at the poles. And of course at the top of a mountain on/near the equator, slightly weaker again.

## Is gravity a push or a pull?

In general relativity, gravity neither pushes nor pulls.

## Does gravity pull you down from below or push you down from above?

As you travel away from the Earth’s surface, your mass stays the same but your weight reduces as gravitational pull decreases. “The experience of weight is through that counteracting force of the ground pushing back on you as you‘re pushing down on the ground, because gravity is pulling you down.

## Is gravity a pull?

Gravity is a force which tries to pull two objects toward each other. Anything which has mass also has a gravitational pull. The more massive an object is, the stronger its gravitational pull is. Earth’s gravity is what keeps you on the ground and what causes objects to fall.

## Could gravity be a push force?

The important thing to remember is that gravity is neither a push nor a pull; what we interpret as a “force” or the acceleration due to gravity is actually the curvature of space and time — the path itself stoops downward.

## Is normal force a push or pull?

For example, when a book is placed on a table, the normal force keeps the book from falling through the table. Gravity is pulling the book downward, but since the book isn’t actually falling, something must be pushing it up. This force is called the normal force.

## Why isn’t gravity a force?

In general relativity, gravity is not a force between masses. Instead gravity is an effect of the warping of space and time in the presence of mass. Without a force acting upon it, an object will move in a straight line. This explains why all objects fall at the same rate.

## Is force a push or pull?

A force is a push or pull upon an object resulting from the object’s interaction with another object. Whenever there is an interaction between two objects, there is a force upon each of the objects. Forces only exist as a result of an interaction.

## What is an example of push?

The definition of a push is the act of putting pressure on someone or something to get action. Push is defined as to press, force or urge a person or thing to move or go away. An example of push is pressing the button for an elevator. An example of push is putting your weight against a couch to move it across the room.

## What is force explain with two examples?

A force involves an interaction between two or more objects, and it causes a push or pull between the objects. Good examples of opposing force include drag due to interaction with an air mass and the force due to friction between two objects.

## What are 4 examples of force?

Common Examples of force are:
• Electric force.
• Magnetic Force.
• Nuclear force.
• Frictional force.
• Normal force.
• Force of Gravity.

## What are the 10 types of forces?

Types of Forces
Contact ForcesAction-at-a-Distance Forces
Frictional ForceGravitational Force
Tension ForceElectrical Force
Normal ForceMagnetic Force

## What does opfor stand for?

An opposing force (alternatively enemy force, abbreviated OPFOR) is a military unit tasked with representing an enemy, usually for training purposes in war game scenarios.

## What does Bluefor mean?

The meaning of BLUEFOR abbreviation is “Blue Force” What does BLUEFOR mean? BLUEFOR as abbreviation means “Blue Force”

## What country is opfor?

This evidence supports the idea that the OpFor nation is, in fact, a fictional Arab Republic, and was created only for story and gameplay purposes. On a television in the mission “Blackout”, a news reporter describes it as a “small, but oil rich country“.
