## Which factors determine how much gravity?

Newton’s law also states that the strength of gravity between any two objects depends on two factors: the masses of the objects and the distance between them.

• Objects with greater mass have a stronger force of gravity between them.
• Objects that are closer together have a stronger force of gravity between them.

## Which factors affect gravitational force check all that apply?

Answer Expert Verified. Only the masses of the objects and the distance between them. Nothing else affects the gravitational forces.

## What does gravity depend on in the universe?

Basically, gravity is dependent on mass, where all things – from stars, planets, and galaxies to light and sub-atomic particles – are attracted to one another. Depending on the size, mass and density of the object, the gravitational force it exerts varies.

## Does rotation affect gravity?

While the spinning of the Earth doesn’t directly affect gravity, it does off-set it a little. At the north and south poles objects weigh exactly what they should, and at the equator things weigh slightly less. The farther you are from the Earth’s axis the more centrifugal force you’ll experience.

## Is anti gravity technology possible?

In the 20th century, Newton’s model was replaced by general relativity where gravity is not a force but the result of the geometry of spacetime. Under general relativity, anti-gravity is impossible except under contrived circumstances.

## Is rotation necessary for gravity?

Rotation, however, isn’t necessary for gravity. 2 and 3) Any object is completely stationary from its own point of view.

## Can centrifugal force overcome gravity?

The centrifugal force is real enough in the rotating frame. (When observed outside of the rotating frame, the force is replaced with an acceleration). It counters the force of gravity because gravity is not changed.

## Can there be zero gravity on Earth?

Contrary to popular belief, there’s no such thing as zero gravity. Weightlessness and zero gravity are two different things. The earth’s gravity keeps the moon in orbit. And astronauts are generally much closer to earth than the moon is, which means that the earth’s pull on them has to be much stronger.

## What does it feel like in zero gravity?

Absence of gravity is known as weightlessness. It is like floating, the feeling you get when a roller coaster suddenly goes down. Astronauts on the International Space Station are in free fall all the time. The astronauts inside it experience weightlessness, floating around in no particular direction.

## What is a zero gravity position?

The zero-gravity (or Zero-G) position is a neutral body posture initially developed by NASA. It’s defined as being in a state or condition of weightlessness. NASA puts astronauts in this position before take-off to equalize their weight and ease the stress on their bodies as they are launched into space.

## What does sleeping in zero gravity do?

Zero Gravity is a great way to take pressure off the heart, allowing for better blood flow throughout the body, while poor, unaligned sleeping positions can actually put additional pressure on the heart. Decrease lower back pain.

## What are the pros and cons of an adjustable bed?

Pros & Cons of An Adjustable Electric Bed

• Increased Comfort. Electric adjustable beds provide increased comfort when compared to conventional beds.
• Pain Relief.
• Independence.
• Combat Snoring.
• Improved Sleep Quality.
• Easier Egress.
• Incompatible with existing mattress.
• More expensive.

## Is zero gravity chair good for back pain?

Zero gravity chairs can relieve back pain by reducing the stress on the back. This is because zero gravity chairs use a reclining position, rather than a sitting position. Zero gravity chairs can be used by people who suffer from back and neck pain. In addition, it also improves blood circulation.
