Question about relativistic motion

In summary, the conversation discusses the question of finding the relative speed of two bodies in space moving towards each other at a speed of C/2. The classical view suggests the relative speed should be C, but the actual answer can be found using the relativistic formula for velocity addition. The formula is u' = (u1 + v1)/(1 - u1*v1/c^2) and when u1 and v1 are substituted with c/2, the answer can be determined.

I have this question .

There are two bodies in space . Each are moving with a speed of C/2 towards each other . What is the relative speed of one body with respect to the other .

According to classical view it has to be C but in real it doesn't can any1 tell me how to find the answer .:rolleyes:

u' = (u1 + v1)/(1 - u1*v1/c^2) where u1, v1 are velocities... this reduces to u' = u1 + v1 classically. substitute u1 = c/2, u2 = c/2, etc. and you have your answer.
 

What is relativistic motion?

Relativistic motion refers to the movement of objects at speeds approaching the speed of light. It takes into account the principles of special relativity, which state that the laws of physics should be the same for all observers moving at constant velocities.

What is the difference between relativistic and classical motion?

The main difference between relativistic and classical motion is the speed at which the objects are moving. Classical motion deals with objects moving at speeds much slower than the speed of light, while relativistic motion deals with objects moving at speeds close to or at the speed of light.

How do we measure relativistic motion?

Relativistic motion can be measured through various methods, including using instruments such as accelerometers, clocks, and laser interferometers. The effects of relativistic motion, such as time dilation and length contraction, can also be observed and measured in experiments.

What are some real-world applications of relativistic motion?

Relativistic motion has several practical applications, including GPS technology, particle accelerators, and space travel. It has also been used in studying the behavior of high-speed particles and in the development of theories such as the Big Bang theory and black holes.

Are there any limitations to relativistic motion?

While the principles of special relativity accurately describe the behavior of objects moving at high speeds, they do not apply to phenomena such as gravity and accelerated motion. Additionally, the effects of relativistic motion are only noticeable at speeds approaching the speed of light, making it difficult to observe in everyday situations.
