## Can we create gravity?

Artificial gravity can be created using a centripetal force.

A centripetal force directed towards the center of the turn is required for any object to move in a circular path.

In the context of a rotating space station it is the normal force provided by the spacecraft’s hull that acts as centripetal force..

## What is the force of gravity on Earth?

9.807 m/s²Earth/Gravity

## What is the other name for gravitational force?

The most common other name used for gravitational force is simply gravity.

## Why is gravity called a force?

6 Answers. Gravity is viewed as a force because it is a force. A force F is something that makes objects of mass m accelerate according to F=ma. … Einstein explained this gravitational force, F=GMm/r2, as a consequence of the curved spacetime around the massive objects.

## What is gravity’s formula?

The formula is F = G*((m sub 1*m sub 2)/r^2), where F is the force of attraction between the two bodies, G is the universal gravitational constant, m sub 1 is the mass of the first object, m sub 2 is the mass of the second object and r is the distance between the centers of each object.

## What is the best example of gravity?

Some examples of the force of gravity include:The force that holds the gases in the sun.The force that causes a ball you throw in the air to come down again.The force that causes a car to coast downhill even when you aren’t stepping on the gas.The force that causes a glass you drop to fall to the floor.More items…

## How fast is 1g force?

For example: An acceleration of 1 g equates to a rate of change in velocity of approximately 35 kilometres per hour (22 mph) for each second that elapses.

## How weight is different from mass?

The mass is essentially “how much stuff” is in an object. … Weight: There is a gravitational interaction between objects that have mass. If you consider an object interacting with the Earth, this force is called the weight. The unit for weight is the Newton (same as for any other force).

## Why is gravity not 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.

## Who invented gravity?

Sir Isaac NewtonSir Isaac Newton was an English mathematician and mathematician and physicist who lived from 1642-1727. The legend is that Newton discovered Gravity when he saw a falling apple while thinking about the forces of nature.

## Is gravity just a theory?

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.

## Why is gravity so weird?

Why is gravity so weird? No force is more familiar than gravity — it’s what keeps our feet on the ground, after all. And Einstein’s theory of general relativity gives a mathematical formulation for gravity, describing it as a “warping” of space.

## What is the force of gravity in Newtons?

G represents the gravitational constant, which has a value of 6.674⋅10−11N(m/kg)2 6.674 ⋅ 10 − 11 N (m/kg) 2 . Because of the magnitude of G , gravitational force is very small unless large masses are involved.

## What is gravity short answer?

The answer is gravity: an invisible force that pulls objects toward each other. Earth’s gravity is what keeps you on the ground and what makes things fall. … Gravity also gets weaker with distance. So, the closer objects are to each other, the stronger their gravitational pull is. Earth’s gravity comes from all its mass.

## Is gravity a force or acceleration?

Gravity is a force that causes acceleration. It is measured by the force that it applies per kg of matter. On earth, 9.8 Newtons of force are applied to each kilogram of mass.

## What is a simple definition of gravity?

Gravity, also called gravitation, in mechanics, the universal force of attraction acting between all matter. … On Earth all bodies have a weight, or downward force of gravity, proportional to their mass, which Earth’s mass exerts on them. Gravity is measured by the acceleration that it gives to freely falling objects.

## What is another word for force?

other words for forceeffort.strength.violence.clout.enforcement.fury.speed.strain.

## Where is gravity the strongest?

Gravity is strongest at the Earth’s surface, and its weakest at the Earth’s core.
