Special relativity relating 3 dimensions

In summary, the coordinates of the event in frame S' are x'= 263.6m, y'= 10m, z'= 1m, and t'= 0.000495s. This can be calculated using the Lorentz transformation equations, specifically x'=y(x-Bct) and t'=y(t-Bx/c^2), where y=1/√(1-v^2/c^2)=1.9208 and B=v/c=0.92.

Homework Statement


An event happens in frame S at x=100m y= 10m z=1m at time t=2*10^-3s. What are the coordinates of this event in rame S' that is moving with velocity v=0.92c (ihat) and the orgins coincide at time t=0.


Homework Equations



Lorentz transformations

The Attempt at a Solution



I would think to do length contraction just in the x-axis but I don't think that is right.
Im not entirely sure how to boost from S to the frame S"

Why don't you just use the straight Lorentz Transformation equations?

Which ones?
x'=y(x-Bct)?

Yes. But you can also use the other LT equation to give you the t' coordinate of the event.

that is moving with velocity v=0.92c (ihat) and the origins coincide at time t=0.

To solve this problem, we can use the Lorentz transformations, which relate coordinates and time between two frames of reference moving at a constant velocity relative to each other. We can use the Lorentz transformations for the x, y, and z coordinates separately.

For the x-coordinate, we have:

x' = γ(x - vt)

Where γ is the Lorentz factor, given by γ = 1/√(1 - v^2/c^2) and v is the velocity of frame S' relative to frame S.

Substituting in the values given in the problem, we have:

x' = (1/√(1-0.92^2)) * (100m - 0.92c * 2*10^-3s)

x' = 245.9m

Similarly, for the y-coordinate, we have:

y' = y

Substituting in the given value of y, we have:

y' = 10m

And for the z-coordinate, we have:

z' = z

Substituting in the given value of z, we have:

z' = 1m

Therefore, the coordinates of the event in frame S' are x' = 245.9m, y' = 10m, and z' = 1m.
 

1. What is special relativity?

Special relativity is a theory developed by Albert Einstein that describes the relationship between space and time. It states that the laws of physics are the same for all observers in uniform motion, and the speed of light is constant for all observers.

2. How does special relativity relate to 3 dimensions?

Special relativity applies to all dimensions, including three-dimensional space. It explains how the measurement of time and space can vary for different observers depending on their relative velocities.

3. What is the concept of time dilation in special relativity?

Time dilation is the phenomenon in which time appears to pass slower for an observer who is moving at high speeds relative to another observer. This is a fundamental consequence of special relativity and is supported by experiments such as the famous "twin paradox".

4. How does special relativity affect our understanding of causality?

Special relativity challenges our traditional understanding of causality by showing that the concept of simultaneous events is relative. Two events that appear simultaneous to one observer may not be simultaneous to another observer in a different frame of reference. This can lead to seemingly paradoxical situations, such as the "pole in a barn" paradox.

5. Can special relativity be applied to everyday situations?

Yes, special relativity has been extensively tested and is a crucial factor in the functioning of technologies such as GPS. Everyday situations involving high speeds and precise measurements, such as air travel and satellite communication, require the use of special relativity to be accurate.
