A frame of reference, in physics, is a particular choice of coordinate systems. Part of what Einstein's theory of relativity is about is that there's no such thing as a "preferred frame" ... one that is somehow "better" than any other. We're therefore free to choose our coordinate system in any way that makes the mathematics convenient for our calculations.

A moving frame is one that's in motion relative to something else ... and since pretty much everything is moving relative to something else, we usually use the term when we're temporarily pretending that there's some "absolute" coordinate system, and we want to describe a frame of reference that's moving relative to that coordinate system. For example, we might use it to describe the frame of reference of people in a spaceship relative to a "static" frame of an observer on a planet.

What is the difference in static frame and moving frame?

The difference in static frame and moving frame is the position of the camera. In static frame the camera stays in one place. With a moving frame the camera is moving and panning the scene.

What is a frame of reference?

A frame of reference is a system used to define location or state for physical objects. A reference frame is a system of objects that are not moving with respect to one another.


Can a moving object be selected as a reference object?

Any moving object can be redefined as a frame of reference at rest, from which all other moving frames can be measured. That's a fundamental precept of Relativity. It's motion is defined only in relation to some other object from which the motion is measured, so reselection as the rest frame is necessary, but once established as a rest frame, it is (for the purpose of measurement) no longer considered to be in motion. Since everything is moving in relation to everything else, any frame can be selected as the frame of reference at rest, with all other motion measured relative to it.


How can you be both at rest and moving at 1000 mph?

Everything is always moving. Even when you think you're standing still, you're actually speeding through space. Your moving relative to the sun and stars- though you are at rest relative to the earth. Right now your speed relative to the sun is about 100,000 kilmeters per hour. And you're moving faster relative to the center of our galaxy. Gotten From : "Conceptual Physical Science - Exploration" Pg 21. Chapter 2. By: Paul G.Hewitt John Suchocki Leslie A. Hewitt

What movement in relation to a frame of reference called?

The movement in relation to a frame of reference is called relative motion. A frame of reference is a system of object that are not moving with respect to one another.
