Is it possible to create a gravity field?
Artificial gravity can be created using a centripetal force.
Thus, the “gravity” force felt by an object the centrifugal force perceived in the rotating frame of reference as pointing “downwards” towards the hull..
Is upthrust a non contact force?
Upwards forces from water or air are called upthrust. Things float in water because of upthrust. … They are called non- contact forces.
Is gravity just a theory?
Gravity 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 masses moving along geodesic lines in a curved spacetime caused by the uneven distribution of mass.
What are the 3 types of non-contact forces?
Examples of Non-Contact Forces are:Gravitational force.Magnetic force.Electrostatics.Nuclear force.
What is the G in physics?
“Big” G is Newton’s gravitational constant and gives the constant of proportionality in Newton’s Universal law of gravitation which is the basis of our understanding of non-relativistic gravity.
Why is gravity not a force?
In general relativity, gravity is not a force between masses. Instead gravity is an effect of the warping of space and time in the presence of mass. Without a force acting upon it, an object will move in a straight line. … This explains why all objects fall at the same rate.
Is electricity a non contact force?
Attraction and repulsion of electric charges is one of three fundamental non-contact forces in nature. The others are magnetism and the force of gravity (see the focus idea Forces without contact).
What type of force is gravity?
Gravity, also called gravitation, in mechanics, the universal force of attraction acting between all matter. … On Earth all bodies have a weight, or downward force of gravity, proportional to their mass, which Earth’s mass exerts on them. Gravity is measured by the acceleration that it gives to freely falling objects.
What are the 3 field forces?
Field forces are also called noncontact forces or at-a-distance forces. There are four types of field forces: gravity, electromagnetic forces, and the strong force and the weak force found in atoms.

How fast is gravity?
The best results, at the present time, tell us that the speed of gravity is between 2.993 × 10^8 and 3.003 × 10^8 meters per second, which is an amazing confirmation of General Relativity and a terrible difficulty for alternative theories of gravity that don’t reduce to General Relativity! (Sorry, Newton!)
Is gravity a vector field?
The gravitational field g (also called gravitational acceleration) is a vector field – a vector at each point of space (and time). … The gravitational flux through any closed surface is proportional to the enclosed mass.
Where is gravity the strongest?
Arctic OceanHirt’s model pinpoints unexpected locations with more extreme differences. Mount Nevado Huascarán in Peru has the lowest gravitational acceleration, at 9.7639 m/s2, while the highest is at the surface of the Arctic Ocean, at 9.8337 m/s2.
What are two contact forces examples?
Examples of contact forces include:Reaction force. An object at rest on a surface experiences reaction force . … Tension. An object that is being stretched experiences a tension force. … Friction. Two objects sliding past each other experience friction forces. … Air resistance.
Is gravity a field or contact force?
The most familiar non-contact force is gravity, which confers weight. In contrast a contact force is a force applied to a body by another body that is in contact with it. All four known fundamental interactions are non-contact forces: Gravity, the force of attraction that exists among all bodies that have mass.
How gravitational force is a field force?
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 the gravitational force decreases as the distance from the object increases.
What are the types of field?

Is magnetic a field force?
Two objects containing charge with the same direction of motion have a magnetic attraction force between them. … In our article on magnetic fields we learned how moving charge surrounds itself with a magnetic field. In this context the magnetic force is a force that arises due to interacting magnetic fields.
