## Which force is attractive in nature?

Gravitational forceAssertion : Gravitational force is always attractive in nature, while electromagnetic force can be attractive or repulsive..

## Can you remove gravity?

Gravity is Earth’s incredible mass pulling matter toward its center. It pulls down on me with around 200lbs of force. The only way to remove that is to make the chamber fall at gravity’s accelleration, or to exit the pull of Earth’s gravity completely. … It is impossible to eliminate gravity.

## What is more powerful than gravity?

The strong nuclear force, also called the strong nuclear interaction, is the strongest of the four fundamental forces of nature. … times stronger than the force of gravity, according to the HyperPhysics website. And that’s because it binds the fundamental particles of matter together to form larger particles.

## Why is gravity attractive?

Gravity is always attractive, because masses of like “charge” attract. … The other way you could have repulsive gravitation would be to have an object that actually has a negative mass or negative energy density – it would push away ordinary positive mass objects.

## Can you make a zero gravity room?

Contrary to popular belief, NASA does not have “anti-gravity chambers” where people can float around like astronauts on the space station. But we do use several facilities to recreate the weightless, or microgravity, conditions of orbit. … It is NASA’s premier facility for conducting ground-based microgravity research.

## Is dark energy repulsive gravity?

The leading theory to explain the accelerating expansion is the existence of a hypothetical repulsive force called dark energy. … “We are replacing an unknown force caused by an unknown element with the repulsive gravity of the well-known antimatter.” (Related: “Dark Matter Is an Illusion, New Antigravity Theory Says.”)

## 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.

## What is the force between two like poles?

Since a magnet has two poles, it is sometimes called a magnetic dipole, being analogous to an electric dipole, composed of two opposite charges. The like poles of different magnets repel each other, and the unlike poles attract each other.

## 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.

## Why is gravity so weird?

2. 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 actually creates gravity?

The answer is gravity: an invisible force that pulls objects toward each other. … So, the closer objects are to each other, the stronger their gravitational pull is. Earth’s gravity comes from all its mass. All its mass makes a combined gravitational pull on all the mass in your body.

## Can gravity be repulsive?

For a repulsive gravitational force, the source of the field must be a negative mass. … Again, all these are just theory, and nobody has actually observed negative mass, but yes, if negative mass exists, then gravity can be repulsive.

## Why gravity is not repulsive?

This theory holds that it is the altered shape of space, deformed by massive objects, that causes gravity, which is actually a property of deformed space rather than being a true force. … Both general relativity and Newtonian gravity appear to predict that negative mass would produce a repulsive gravitational field.

## Which forces are attractive or repulsive?

The Coulomb force between two or more charged bodies is the force between them due to Coulomb’s law. If the particles are both positively or negatively charged, the force is repulsive; if they are of opposite charge, it is attractive. This called Coulomb’s law and was the first attempt to understand the electric force.

## Why do bodies attract each other?

Since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. So as the mass of either object increases, the force of gravitational attraction between them also increases.

## Can gravity push?

As a curvature, or warping of spacetime, gravity is neither a push nor a pull. Astronauts in orbit float freely, i.e., force-free, under the influence of gravity, even though they seem to be pulled in an accelerated path around the earth.

## Which forces can be attractive?

Electric and magnetic (electromagnetic) forces can be attractive or repulsive, and their sizes depend on the magnitudes of the charges, currents, or magnetic strengths involved and on the distances between the interacting objects. Gravitational forces are always attractive.

## Are repulsive forces negative?

The force of the interaction between the charges is attractive if the charges have opposite signs (i.e., F is negative) and repulsive if like-signed (i.e., F is positive).
