What do you mean by gravitational field which are the factors influencing it?

Factors That Influence the Strength of 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.

What do the lines of the gravitational field inform about?

In a field line diagram, the direction of the field line at a point gives the direction of the force of attraction that would be felt by a small mass placed there. The relative density of field lines on the diagram is an indication of the strength of the field.

How does gravitational field affect light?

Gravity bends light Light travels through spacetime, which can be warped and curved—so light should dip and curve in the presence of massive objects. This effect is known as gravitational lensing GLOSSARY gravitational lensingThe bending of light caused by gravity .

Where does the gravitational influence?

It also explains other ways in which spacetime behaves. The behavior of spacetime depends on how much mass and energy is present, how it is distributed, and how it is moving. On the scale of groups of galaxies and smaller, there is enough localized mass present to make spacetime act like traditional gravity.

What are the factors that affect gravitational potential energy?

Gravitational Potential Energy is determined by three factors: mass, gravity, and height. All three factors are directly proportional to energy.

What is gravitational line?

The line of gravity is an imaginary vertical line from the centre of gravity to the ground or surface the object or person is on. It is the direction that gravity is acting upon the person or object.

What is gravitational field in physics?

In physics, a gravitational field is a model used to explain the influences that a massive body extends into the space around itself, producing a force on another massive body. Thus, a gravitational field is used to explain gravitational phenomena, and is measured in newtons per kilogram (N/kg).

How are massless particles affected by gravity?

Massless particles are known to experience the same gravitational acceleration as other particles (which provides empirical evidence for the equivalence principle) because they do have relativistic mass, which is what acts as the gravity charge.

What is gravitational force in physics?

The gravitational force is a force that attracts any two objects with mass. We call the gravitational force attractive because it always tries to pull masses together, it never pushes them apart. In fact, every object, including you, is pulling on every other object in the entire universe!

What is gravitational force in geography?

Definitions of gravitational force. (physics) the force of attraction between all masses in the universe; especially the attraction of the earth’s mass for bodies near its surface. synonyms: gravitation, gravitational attraction, gravity.

How do magnetic fields affect atomic energy levels and spectral lines?

The atomic energy levels, the transitions between these levels, and the associated spectral lines discussed to this point have implicitly assumed that there are no magnetic fields influencing the atom. If there are magnetic fields present, the atomic energy levels are split into a larger number of levels and the spectral lines are also split.

What is the gravitational field in physics?

The gravitational field is the gravitational force per unit mass that would be exerted on a small mass at that point. It is a vector field, and points in the direction of the force that the mass would feel.

What happens when a magnetic field is present?

If there are magnetic fields present, the atomic energy levels are split into a larger number of levels and the spectral lines are also split. This splitting is called the Zeeman Effect. The pattern and amount of splitting are a signature that a magnetic field is present, and of its strength.

How does gravity affect the shape of light coming from galaxy clusters?

In 2011 the group of Radek Wojtak of the Niels Bohr Institute at the University of Copenhagen collected data from 8000 galaxy clusters and found that the light coming from the cluster centers tended to be red-shifted compared to the cluster edges, confirming the energy loss due to gravity.
