Gravitational force -an attractive force that exists between all objects with mass; an object with mass attracts another object with mass; the magnitude of the force is directly proportional to the masses of the two objects and inversely proportional to the square of the distance between the two objects.

## How does mass attract other mass?

The Law of Universal Gravitation states that every point mass attracts every other point mass in the universe by a force pointing in a straight line between the centers-of-mass of both points, and this force is proportional to the masses of the objects and inversely proportional to their separation This attractive …

## Can 2 masses repel each other?

So the more mass a body has in the space, with much more force it attracts the other bodies.. This is the reason for any relativistic masses to be attracted to each other… but not repel one another.. Electrons, which are masses, do repel each other.

## Why does one mass attract each other?

Two point masses or objects always attract each other because of the presence of gravitational force . gravitational force is a force of attraction between two bodies which is directly proportional to product of there masses and inversely proportional to the squre of the distance between that two particles.

## What two things attract each other?

Positively charged objects and neutral objects attract each other; and negatively charged objects and neutral objects attract each other.

## Do all masses attract each other?

All objects attract each other with a force that is directly proportional to the product of their masses and inversely proportional to their distance of separation.

## What is the difference between mass and weight?

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).

## Is negative matter real?

In theoretical physics, negative mass is a type of exotic matter whose mass is of opposite sign to the mass of normal matter, e.g. −1 kg. Currently, the closest known real representative of such exotic matter is a region of negative pressure density produced by the Casimir effect. …

## Can mass ever be zero?

Mass can be zero. Both photons (bosons of the electromagnetic force) and gluons (bosons of the strong force) are massless. Mass is not a necessary or intrinsic property of matter (by the better definitions).

## Is negative weight possible?

Weight is a vector quantity so it can be either positive or negative, with respect to reference it can be positive or negative.

## Does gravity attract mass?

Gravity attracts any form of mass or energy, including all fundamental particles, photons, and even kinetic energy.

## Does gravity always attract?

Gravity is always attractive force because as 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 the curvature of spacetime caused by the uneven distribution of mass.

## Does light have mass?

Light indeed carries energy via its momentum despite having no mass. … Since photons (particles of light) have no mass, they must obey E = pc and therefore get all of their energy from their momentum. Now there is an interesting additional effect contained in the general equation.

## What causes 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.

## Does gravity use energy?

Gravity has no energy, it’s just a force. A force requires no energy to maintain. It’s when a force acts through a distance, then that requires energy.

## What causes objects to attract?

The attraction occurs when two objects of opposite charge are in close proximity, and the electrical force causes these objects to attract. Therefore, positive and negative charges will attract each other. … The third force that may cause attraction is the magnetic force.
