### What is the importance of gravitational field in our daily

• What is the importance of gravitational field in our daily life? Gravity also is important on a larger scale. It is the Sun's gravity that keeps the Earth in orbit around the Sun. Life on Earth needs the Sun's light and warmth to survive. Gravity helps the Earth to stay just the right distance from the Sun, so it's not too hot or too cold
• The study of gravitational field is important because, it used to explain the influence 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)
• A gravitational field like any other force field is responsible for the force on a body. The gravitational fields originate from all the massive bodies and result in the attractive pull known as..
• In this chapter we begin the study of the gravitational fields in the framework of the general theory of relativity. The force of gravity is an unscreened long-range force, and it can be considered as an intrinsic property of the space-time related to the space-time geometry
• The Earth's gravitational field is important primarily because Without gravity, life would cease to exist
• Gravity is the field around the Earth that can be measured by satellites. Changes in the gravity field are related to change or transportation of mass, which can provide information on ocean circulation, glacial melt, droughts or geodesy

The gravitational force is very important to keep the universe functioning. The planets revolve around the Sun because of the force of gravity Galaxies exist also due to gravitational force. It is the force of gravity that starts the nuclear fusion in stars. Stars exist due to gravitational force However, gravitational waves change the length of the interferometer's arms by an incredibly tiny amount: roughly 1/10,000th the width of an atom's nucleus. To pick up such a tiny change, LIGO. What Is a Gravitational Field? A gravitational field is the force field that exists in the space around every mass or group of masses. This field extends out in all directions, but the magnitude of.. Interaction between the gravitational field and anelastic solid body became quite an important subject in astrophysical applications, since the discovery that, due to a process of crystallization of dense neutron matter, neutron stars and white dwarfs are solid (or partly solid) objects (see, e.g. Refs. [1,2]) In physics science a gravitational field is the influence that a massive body extends into the space around itself, producing a force on another massive body. So in other terms, a gravitational field helps us to explain the gravitational phenomena and is measured in newtons per kilogram (N/kg). Sir Isaac Newton discovered gravity and its forces

1. Gravitational Force. Commonly referred to as gravity, it is important to encourage the use of the correct term, 'gravitational force'. In the SPACE research report 'Forces' (Russell, et al 1998) clear stages in the progression of children's understanding of gravitational force and associated phenomena are identified
2. ation from gravitational lensing signals.The results should lead to more accurate cosmological models of the universe, said Dr. Mustapha Ishak-Boushaki, professor of physics in the School of Natural Sciences and.
3. Pinpointing the sources of gravitational waves will allow astronomers to point other telescopes their way, boosting the chances of learning more about them via x-rays, gamma-rays, radio waves.
4. Gravity is what holds the planets in orbit around the sun and what keeps the moon in orbit around Earth. The gravitational pull of the moon pulls the seas towards it, causing the ocean tides. Gravity creates stars and planets by pulling together the material from which they are made. Gravity not only pulls on mass but also on light

1. One mysterious gravitational anomaly is in the Hudson Bay of Canada (shown above). This area has lower gravity than other regions, and a 2007 study finds that now-melted glaciers are to blame
2. Gravitational lensing works in an analogous way and is an effect of Einstein's theory of general relativity - simply put, mass bends light. The gravitational field of a massive object will extend far into space, and cause light rays passing close to that object (and thus through its gravitational field) to be bent and refocused somewhere else
3. Don't let the name fool you: a black hole is anything but empty space. Rather, it is a great amount of matter packed into a very small area - think of a star ten times more massive than the Sun squeezed into a sphere approximately the diameter of New York City. The result is a gravitational field so strong that nothing, not even light, can escape
4. Gravitational field lines help us to imagine what sort of forces would act on a particle at a certain point near another gravitating object. The direction of the field lines indicates the direction of the force that a mass would experience if placed at a certain point, and the density of the field lines is proportional to the strength of the force
