rotation and revolution of earth provide the framework for measuring time. so the answer is the motions of earth.

Can Acceleration be used as a frame of reference?

Acceleration is not typically used as a frame of reference in physics. It is a physical quantity that describes how an object's velocity changes over time. In contrast, frames of reference are used to define the position and motion of objects relative to a chosen point or system.


What is movement in relation to a frame of reference called?

Relative motion is movement in relation to a frame of reference.


If we witness events in a frame of reference moving past us time appears to be stretched (or dilated). How do the lengths of objects in that frame appear?

In the frame of reference moving past us, lengths of objects appear contracted in the direction of motion. This effect is known as length contraction and is a consequence of Einstein's theory of relativity where measurements of length depend on the observer's relative motion.


What can time depend on?

Time can depend on the observer's reference frame, the speed of the object being observed (according to the theory of relativity), and the presence of gravity. Additionally, the measurement of time can be influenced by factors such as the accuracy of the clock being used and any external forces acting on the system.


What is a frame of reference in physics?

A frame of reference is your position relative to the action you are observing. Lets say two people are playing ping-pong on a bus. One frame of reference would be another person on the bus, another would be a person on the sidewalk. Although they are observing the same thing, they would see different things. A true inertial frame of reference in physics is a still non-moving point of observation. A frame of reference is either a true inertial frame of reference, or a relative inertial frame of reference, relative in some form of measurement to the true inertial frame of reference. However this indicates a beginning still point in time to measure both time and motion from. After Einstein showed that E=mc2 and that time is relative to space the search for a true inertial frame of reference was abolished and Einstein spent the rest of his life trying to resolve the problems eliminating constant time created and stated that "God does not play dice with the Universe". Most physicists disagree and are quite happy with a game of dice, but Einstein knew he was right and the answer would be found in unifying EM and gravity. He was right. U(1) contains gravity (and Mass) but finds itself outside the weak force. EM=electric force + gravity. See Unified Field Theory The mistake Einstein made was he considered a true observer which means Life, as a non-element. Something that could be eliminated and leave the Universe intact. Real Relativity reverses the symmetry in time and states: "Time is not relative to multiple observers at the same time. Time is relative to a single observer in multiple places in time." This restores constant time motion is relative to and establishes a true or "initial" inertial frame of reference. A joke in real relativity regarding the inertial frame of reference states: "Since it is not moving one can not ask where it came from and since it has no inertia an observer is required to explain the contradiction and have a point of view." "Relative to an initial inertial frame of reference there is only one observer." is the first law in Real Relativity. In Real Relativity I=E/R is converted to S=Wp/T Space, Time, Weak pressure: weight of the Observer's Mass: gravity contained within the weak force. Real Relativity has been accepted by the top leading sound technicians and musicians that learn of it and resulted in correcting the old Circle of Fifths creating the " New Circle of Fifths" where tonal space is relative to real time to start a list of new features. The NC5 is gravity based and turned to show the minor keys. Numbers don't tell lies...never have and never will. Same goes for gravity. Time is relative to the observer and gravity is a product of time...LIGO is pointing in the wrong direction.

Why time is independent of any reference frame?

According to the Theories of Relativity, time is NOT independent of the reference frame.


What item is used to measure time?

According to Einstein time is one component of "spacetime" and therefore its measurement is relative to your frame of reference. In your frame of reference you would measure it in seconds and you may use a chronometer to measure it.

Are time dilation and length contraction noticed inside a single frame of reference?

Yes, when an object moving through that frame is measured.

There is no exact time frame yet agreed upon.


Define frame of reference?

Frame of reference is used to delineate that differing perspectives will have different interpretations. Consciousness concerning frame of reference is useful when evaluating the validity of claims.

What date do you have to put on an authorization letter?

The date of a letter should always be the date that the letter is sent. If there is a time frame that an authorization will be effective, that time frame should be stated in the content of the letter or a reference line before the start of the letter.
