Inertial frames are reference frames in which a free object either remains at rest or moves at a constant velocity unless acted upon by an external force. They are characterized by the absence of any acceleration in the absence of external forces. According to Newton's first law of motion, an inertial frame is one where an object not subject to external forces moves at a constant velocity in a straight line.
What else can I help you with?
Is earth inertial or noninertial frame?
Earth is considered a noninertial frame of reference due to its rotation and orbital motion. Inertial frames are frames of reference where Newton's laws of motion hold true without the influence of external forces, which is not the case for Earth.
What is the role of pseudoforces in the dynamics of a non-inertial reference frame?
Pseudoforces, also known as fictitious forces, are forces that appear to act on objects in non-inertial reference frames, which are frames of reference that are accelerating. These forces are not real forces but are necessary to explain the motion of objects in these frames. Pseudoforces help account for the apparent acceleration of objects in non-inertial reference frames and are essential for accurately describing the dynamics of such systems.
What is the role of fictitious force in explaining the motion of objects in non-inertial reference frames?
Fictitious forces are imaginary forces that appear in non-inertial reference frames to explain the motion of objects. They are used to account for the acceleration experienced by objects in these frames, helping to accurately describe their motion despite the frame's acceleration.
What is the difference between inertial reference frame and absolute reference frame?
An inertial reference frame is a frame of reference in which an object not subject to external forces moves at a constant velocity. An absolute reference frame is a hypothetical frame of reference that is fixed in space and in which all other frames of reference are measured. Inertial reference frames are relative to each other, while the absolute reference frame provides a universal standard of motion.
What are the limits to an inertial balance?
An inertial balance can only measure the mass of objects within its weight capacity. It may provide inaccurate readings if subjected to external vibrations or air currents. It is not suitable for measuring extremely small masses or masses in non-inertial reference frames.
Why newton's laws are not valid in non inertial frame of reference?
newtons laws are always valid in non inertial frames

Is newton's third law valid universally?
Only in inertial reference frames.

Does the speed of light is same in all inertial reference frames?
Yes, as long as the light is passing through vacuum.

Is the twin paradox possible if the space twin was in an inertial frames of reference?
No, if both persons are in inertial frames of reference the situation is completely symmetric so the 'paradox' does not occur. Also note that it is not really a paradox because general relativity has a conclusive answer to what happens to the twins. It is; however, not possible to set up a twin paradox-like situation with neither twin never leaving an inertial frame. This is because if they want to move apart, and come back again, they need to accelerate somehow, and the act of acceleration causes you to leave an inertial frame.
What does the theory of special relativity say about the equivalence of different frames of reference?
It says that the speed of light in a vacuum measured in any inertial frame of reference is equivalent to the speed of light in a vacuum measured in any other inertial frame of reference.
What are the two frames of reference you use today on the earth?
The two frames of reference commonly used on Earth are the inertial frame of reference, which is a non-accelerating frame, and the rotating frame of reference, which takes into account the Earth's rotation. Both frames are important in physics for describing motion and dynamics accurately.
What are lorentz transformatios in non-inertial frame?
It's unfortunate that this system does not allow mathematical notation, so these have to be at least partly spelled out. Some definitions: t0 refers to time interval as measured in an inertial frame t refers to the relative non-inertial time measurement m0 and m for mass, and L0 and L for length (along the direction of travel) follow the same pattern t = t0/the square root of [1-(v/c)2] m = m0/the square root of [1-(v/c)2] L = L0{the square root of [1-(v/c)2]} The lorentz transformations, by definition, compare the relationship between non-inertial frames and their designated inertial reference frames.
