I'm 11 and I'm trying understand what Special Relativity is about. How many different inertial frames of reference do we have and what are they?? I know what it means.
I am afraid you are missing something in your formulation. Or maybe you have too much.HallsofIvy said:You are in an "inertial frame of reference" as long as there are exterior force on you and you are moving, relative to some point, at a constant velocity. Any two frames of reference, moving at constant velocity relative to each other, are "different inertial frames of reference".
nasu said:I don't think the force requirement is necessary, as stated. You can have many forces acting of you and still moving with constant velocity.
It is the net force which has to be zero in order to have constant velocity in an inertial frame.

An inertial frame of reference is a coordinate system in which an object will remain at rest or move with constant velocity unless acted upon by an external force. In other words, an inertial frame of reference is a frame of reference where Newton's first law of motion holds true.
In special relativity, the laws of physics are the same in all inertial frames of reference. This means that an observer in one inertial frame of reference will measure the same physical phenomena as an observer in another inertial frame of reference, regardless of their relative velocities.
Yes, an inertial frame of reference can be moving. As long as the frame is not accelerating, it can be considered an inertial frame of reference. This means that an observer in the moving frame will still measure the same physical phenomena as an observer in a stationary frame, as long as they are not accelerating.
In an inertial frame of reference, time dilation occurs when an object is moving at a high velocity relative to an observer in another inertial frame. This means that time will appear to move slower for the moving object compared to the stationary observer. This is a consequence of special relativity and can be observed in experiments such as the famous "twin paradox".
Yes, there are many real-life applications of understanding inertial frames of reference and special relativity. Some examples include global positioning systems (GPS), particle accelerators, and spacecraft navigation. These systems rely on accurate understanding and calculations of inertial frames of reference and special relativity to function properly.
