Does relativistic mass have gravity?

Energy density (“relativistic mass”) does contribute to gravity – and the fact that the object is moving at relativistic speeds does affect the space-time around it.

Does gravity not exist in general relativity?

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. In the same way, the straight path of an object is bent when space and time is bent.

What is the difference between rest mass and relativistic mass?

The word mass has two meanings in special relativity: invariant mass (also called rest mass) is an invariant quantity which is the same for all observers in all reference frames, while the relativistic mass is dependent on the velocity of the observer.

How does mass cause gravity?

Einstein’s theory of relativity adds to this. According to theory, the reason mass is proportional to gravity is because everything with mass emits tiny particles called gravitons. These gravitons are responsible for gravitational attraction. The more mass, the more gravitons.

What is the relativistic mass in physics?

relativistic mass, in the special theory of relativity, the mass that is assigned to a body in motion. The relativistic mass m becomes infinite as the velocity of the body approaches the speed of light, so, even if large momentum and energy are arbitrarily supplied to a body, its velocity always remains less than c.

How does mass of a relativistic particle vary with its velocity?

The relativistic mass m becomes infinite as the velocity of the body approaches the speed of light, so, even if large momentum and energy are arbitrarily supplied to a body, its velocity always remains less than c.

What is relativistic mass?

Relativistic mass is an obsolete idea, partially because it makes it easy for people to make the same mistake you did: thinking that you get relativistic gravity by plugging relativistic mass into Newtonian gravity. So the normal reaction force is only proportional to the object’s “rest weight” so to speak?

Does energy density contribute to gravity?

Energy density (” relativistic mass “) does contribute to gravity – and the fact that the object is moving at relativistic speeds does affect the space-time around it. There is an interesting document that explains the problem in further context.

What is the relativistic mass of a photon?

A body with rest mass m0turns out to have relativistic mass γm0. But the definition m = p/vnow also neatly defines a relativistic mass for a photon: this moves with speed cand has energy E, and electromagnetic theory gives it a momentum of magnitude p = E/c, so it has relativistic mass p/v = E/c2.

What is the relationship between rest mass and acceleration?

When at rest, the object’s rest mass equals its relativistic mass. When it moves, its acceleration is determined by both its relativistic mass (or its rest mass, of course) and its velocity. The use of these γ-scaled quantities is governed only by the extent to which they are useful.
