Gravitational field & Gravitational field strength A gravitational field is a region in which a mass experiences a force due to gravitational attraction. 1  A gravitational field is a region of space surrounding a body that has the property of mass. 2  In this region, any other body that has mass will experience a force of attraction.ravitational field & Gravitational field strength. Any two bodies in the universe attract each other with a force. This spectacle is called the gravitational attraction. This force of attraction is known as the gravitational force or force due to gravity.

Free fall In a uniform gravitational field, in the absence of any other forces, gravitation acts on each part of the body equally and this is weightlessness, a condition that also occurs when the gravitational field is zero (such as when far away from any gravitating body). A body in free fall experiences 0 g.

Gravitational lens The aqua circle is a source as it would be seen if there was no lens; white spots are the multiple images of the source. A gravitational lens is a distribution of matter (such as a cluster of galaxies) between a distant light source and an observer, that is capable of bending the light from the source as the light travels towards the observer.

Gravitational collapse Gravitational collapse of a massive star, resulting in a Type II supernova. Gravitational collapse is the contraction of an astronomical object due to the influence of its own gravity, which tends to draw matter inward toward the center of mass. Gravitational collapse is a fundamental mechanism for structure formation in the universe.

- Gravity, or gravitation, is a natural phenomenon by which all things with mass are brought toward (or gravitate toward) one another, including planets, stars and galaxies, and other physical objects. Since energy and mass are equivalent, all forms of energy (including light) cause gravitation and are under the influence of it.

Electromagnetic field An electromagnetic field (also EMF or EM field) is a physical field produced by electrically charged objects. It affects the behavior of charged objects in the vicinity of the field. The electromagnetic field extends indefinitely throughout space and describes the electromagnetic interaction.

What is the difference between gravitational potential and gravitational potential energy? Gravitational Potential Energy. Gravitational potential energy is energy an object possesses because of its position in a gravitational field. The most common use of gravitational potential energy is for an object near the surface of the Earth where the gravitational acceleration can be assumed to be constant at about 9.8 m/s 2.

- The electric field at a given point is defined as the (vectorial) force that would be exerted on a stationary test particle of unit charge by electromagnetic forces (i.e. the Lorentz force). A particle of charge would be subject to a force.

Visualizing Gravity: the Gravitational Field The gravitational field outside a uniform sphere is GM/r 2 towards the center. There s an added bonus: since we found this result be adding uniform spherical shells, it is still true if the shells have different densities, provided the density of each shell is the same in all directions.

Gravitational energy Gravitational energy. Gravitational energy is the gravitational potential energy a body with mass has in relation to another massive object. It is potential energy associated with the gravitational field. Gravitational energy is dependent on the masses of two bodies, their distance apart and the gravitational constant (G). In cases where the acceleration is fairly constant, such as dropping a ball on Earth, the Newtonian formula – for the gravitational energy of one of the bodies relative to the other – can be reduced to: =

- A magnetic field is a force field that is created by moving electric charges (electric currents) and magnetic dipoles, and exerts a force on other nearby moving charges and magnetic dipoles. At any given point, it has a direction and a magnitude (or strength), so it is represented by a vector field.

What Are Gravitational Waves And Why Do They Matter? Gravitational waves are disturbances in the fabric of spacetime. If you drag your hand through a still pool of water, you'll notice that waves follow in its path, and spread outward through the pool. According to Albert Einstein, the same thing happens when heavy objects move through spacetime.

Gravitational energy In classical mechanics, two or more masses always have a gravitational potential. Conservation of energy requires that this gravitational field energy is always negative. The gravitational potential energy is the potential energy an object has because it is within a gravitational field.

- I think your question is asking about the gravitational field produced by a moving object. Yes, the grav field of an object moving near the speed of light is greater than when it is at rest. The moving object has a huge amount of kinetic energy. And energy produces gravity, just like mass does.
