What is the difference between gravitational force and electric field




















Unfortunately, this prediction of general relativity has yet to be directly tested or proven to be true. There is a similarity between gravitation and electrostatic force equations. Although this led to speculation that the two forces were somewhat related, differences were seen that separated the forces.

Einstein's and Maxwell's equations indicate that moving charges and moving masses provide an analogy of gravitational and electromagnetic fields, called gravitomagnetics. The result is that large rotating masses affect nearby small masses.

Aug 14, There's plenty of similarities and differences, but I'll point out probably the most significant of each: Similarity: Inverse square laws Both of these fields obey "inverse square laws".

The electric potential is defined as the amount of work on a unit charge that is required to bring the unit charge from infinity to the given point.

Another very important aspect of the electric field is the electric flux density. Electric flux density is a measurement of the number of electric field lines going perpendicular to a given unit area surface. Gravitational field is produced by any mass in the space. There are very important concepts in gravitational fields such as gravitational field intensity and gravitational potential. The gravitational field intensity is also referred as the gravitational acceleration.

Newtonian theory of gravitation is not a very accurate model. Especially, Newtonian solutions deviate notably from the actual values when dealing with high gravity problems. So, Newtonian theory of gravitation is useful only when dealing with low gravity problems.

However, it is accurate enough to be used in most of the practical applications. When dealing with high gravity problems, general relativity must be used. In low gravity, it is approximated to Newtonian theory. Field of a positive electric charge in front of a horizontal perfectly conducting metal surface. Electric field: Electric field is caused by charges or varying magnetic fields. Gravitational field: Gravitational field is caused by masses.
