# What are the main differences between conventional and relative simultaneity?

## What is relative simultaneity?

In physics, the relativity of simultaneity is the concept that distant simultaneity – whether two spatially separated events occur at the same time – is not absolute, but depends on the observer’s reference frame.

## Why is simultaneity relative?

theory of relativity implies that simultaneity is relative to a frame of axes. If one frame of axes is moving relative to another, then events that are simultaneous relative to the first are not simultaneous relative to the second, and vice versa.

## Do any two observers always agree on simultaneity of events Why?

Never since they are both moving. Always only if they occur at the same time. Always only if they occur at the same place and time. Simultaneity is impossible in Relativity.

## How do you find relativity of simultaneity?

Quote from the video:
Youtube quote: Times C minus V equals L over 2 and therefore TB is equal to L over. 2 times C minus V.

## What is the meaning of simultaneity?

adjective. existing, occurring, or operating at the same time; concurrent: simultaneous movements;simultaneous translation.

## What is twin paradox theory?

In physics, the twin paradox is a thought experiment in special relativity involving identical twins, one of whom makes a journey into space in a high-speed rocket and returns home to find that the twin who remained on Earth has aged more.

## Why is simultaneity not absolute?

Simultaneity is not absolute. We might have guessed (incorrectly) that if light is emitted simultaneously, then two observers halfway between the sources would see the flashes simultaneously. But careful analysis shows this cannot be the case if the speed of light is the same in all inertial frames.

## What is meant by the sentence simultaneity is not absolute?

Describe what is meant by the sentence, “Simultaneity is not absolute.” Events may appear simultaneous in all frames of reference. Events may not appear simultaneous in all frames of reference. The speed of light is not the same in all frames of reference.

## Is there absolute simultaneity?

That absolute simultaneity is indeed a special assumption can be seen easily if one looks at Newton’s space and time from a four dimensional point of view. The Newtonian spacetime consists of layers of simultanous events.

## What are the consequences of relativity of simultaneity?

Specifically, Special Relativity showed us that space and time are not independent of one another but can be mixed into each other and therefore must be considered as the same object, which we shall denote as space-time. The consequences of space/time mixing are: time dilation. and length contraction.

## What is the main reason according to special relativity why two events as seen by different inertial observers may not happen simultaneously?

The two events were not simultaneous, according to the new observer. Notice that the reasoning requires the light postulate: both light flashes must move at the same speed; that is, each must require the same time to cover the same distance.

## What is observers frame reference?

In special relativity, an observer is a frame of reference from which a set of objects or events are being measured. Usually this is an inertial reference frame or “inertial observer”.

## What is the difference between reference point and observer?

1 Answer. Show activity on this post. A frame of reference means a co-ordinate system and an observer is someone using that co-ordinate system. For example I could define cartesian co-ordinates (t, x, y, z) and define myself to be at the point (0, 0, 0, 0) and since I’m always at the origin that means I’m at rest.

## Is Earth an inertial frame of reference Brainly?

Answer: Earth is an Inertial Reference Frame as it revolves around the Sun at a constant velocity. But Earth rotating and at the same time revolving at a constant velocity is also due to a centripetal acceleration.

## Is it possible for two observers to describe a motion of a car differently explain?

Special Relativity. Velocity Addition: If observers in two different frames of reference (that are in motion relative to each other) are observing motion of the same object, they will both measure it to be traveling at different speeds.

## What is motion describe that motion is relative how two observers in relative motion can have conflicting views about same object?

Explanation: All motions are relative to some frame of reference. Saying that a body is at rest, which means that it is not in motion, merely means that it is being described with respect to a frame of reference that is moving together with the body.

## What two measurements will two observers in relative motion always agree on?

The two measurements will two observers in the relative motion always agree on the speed of light and the relative speed between them.
