Frames of Reference: Inertial vs Non-Inertial

In summary, a frame of reference is a coordinate system used to measure the position and motion of objects. There are two types of frames - inertial and non-inertial - which are classified based on the presence or absence of external forces. It is important to consider frames of reference in scientific experiments as they allow for accurate analysis and prediction of object behavior. A frame of reference cannot be both inertial and non-inertial, but can transition between the two depending on external forces.

is space an inertial or non inertial frame of reference?

"space" is not a frame of reference at all. You have to pick an object and say " the frame of reference in which this object is at rest"

can u please make me understand why time dilated in space?

Time dilation has nothing to do with space. You, right now as you read this, sitting somewhere on Earth, are MASSIVELY time dilated according to a particle in the CERN accelerator. You are also slightly time dilated according to a fast-moving cosmological body, and you are not time dilated at all according to the chair you are sitting in.

Sorry...!:frown:I can't understand yet . Plz explain it in simple way

This is not a sensible expectation. You can't expect someone on here to teach you a subject or a topic from the beginning. Instead, there are many resources online and in bookstores that will try to teach you pretty much any subject you could imagine.

If you have a specific question, you can ask it here and get some good insights.

No one can "make you understand" something. You have to study it for yourself and then ask if something confuses you.

ok...could u please clarify me that why moving objects with speed of light experiences time dialation?

I can't because the question is nonsense.

@BLUE PEARL, you really need to take the advice offered in post #6 and do some basic reading. Your questions make it clear that you have zero fundamental understanding of these concepts so asking random questions on an internet forum is pointless. You HAVE to get a basic understanding on your own before you can even ask meaningful questions.

As has been said, we cannot teach you everything about a topic. You're going to need to look up some information on your own before we can help you.

Some links to look at:
http://www.pitt.edu/~jdnorton/teaching/HPS_0410/chapters/Special_relativity_principles/
http://www.sparknotes.com/testprep/books/sat2/physics/chapter19section1.rhtml
http://abyss.uoregon.edu/~js/21st_century_science/lectures/lec06.html
http://www.encyclopedia.com/topic/Special_relativity_(Physics).aspx

Give these a thorough reading. Once you've done so, feel free to start a new thread on this subject in the relativity forum. Thread locked.
 

1. What is a frame of reference?

A frame of reference is a coordinate system that is used to measure the position, motion, and other physical quantities of objects. It is a necessary tool in science and physics to describe and understand the behavior of objects in the universe.

2. What is the difference between an inertial and non-inertial frame of reference?

An inertial frame of reference is a coordinate system in which Newton's first law of motion holds true, meaning that objects will remain at rest or in motion with constant velocity unless acted upon by an external force. A non-inertial frame of reference is a coordinate system in which Newton's first law does not hold true, typically because the frame itself is accelerating or rotating.

3. How do you determine if a frame of reference is inertial or non-inertial?

A frame of reference can be classified as inertial or non-inertial based on the presence or absence of external forces acting on the objects within the frame. If there are no external forces (such as friction or gravity), the frame is considered inertial. If there are external forces, the frame is considered non-inertial.

4. Why is it important to consider frames of reference in scientific experiments?

Frames of reference are important because they allow us to accurately describe and predict the behavior of objects in different situations. In many scientific experiments, different frames of reference may be used to analyze the same event, and understanding the differences between inertial and non-inertial frames is crucial in interpreting the results.

5. Can a frame of reference be both inertial and non-inertial?

No, a frame of reference can only be classified as either inertial or non-inertial. If there are external forces acting on the objects within the frame, it is considered non-inertial. If there are no external forces, it is considered inertial. However, a frame of reference can transition from being inertial to non-inertial (or vice versa) if external forces are applied or removed.
