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.
What is an intertial frame of reference?
Assuming you mean "inertial" frame of reference... it is any point of observation from which other objects appear to be still or in motion relative to you. For example... On an airplane flying at 35,000 feet. All the other passengers appear to you to be sitting in their seats or walking down the aisle at a leisurely pace... If you tossed a ball in the air, it would appear to go straight up and fall back into your hand... To someone on the ground, you and all your fellow passengers seem to be hurtling thru the sky at 500 mph. And the path the ball follows is not straight up or down. You and your fellow passengers share the same inertial frame of reference. In a similar sense, the earth under your feet appears to be still and all the objects seem to move or not move in relation to the still earth. In fact the earth is spinning... beyond that it is revolving around the sun, beyond that the entire solar system is moving in a galaxy that is, itself spinning, and the entire galaxy is also moving thru a universe that is expanding... Each of these are other inertial frames of reference. Einstein's theory of relativity states that none of these frames of reference is preferred... and that all observations, including those relating to time, dimension and speed, are entirely relative to one's inertial frame of reference. Thus different observers in different frames of reference perceive things differently. because even time varies with frame of reference, this renders such concepts as simultaneity specious. If time itself passes at different rates for different observers, then no two events can actually be said to happen at the same time.
A frame shift mutation occurs any time a gene mutation results in the insertion or deletion of a number of nucleotides that is not a multiple of three?
false
What graph are used to analyze the motionof an accelerating objects?
On a accelerating body, Velocity and distance of an object are effected. For a graph plotted with Acceleration to Time, it directly gives the acceleration at any given instant. For a graph plotted with Velocity versus Time. The Slope at any instant would give the Acceleration. Or given the time frame, say A to B. Acceleration can be found out by subtracting velocity at A from velocity at B divided by the time frame A to B.
Did ptolemy's model of the universe excluded any reference to heaven?
Ptolemy's model of the universe did not exclude any reference to heaven. Claudius Ptolemy was a Greco-Roman mathematician and writer.
What is movement in relation to a frame of reference called?
Relative motion is movement in relation to a frame of reference.
What is speed of light in a car?
299,792,458 m/s - the same as any other time. Your frame of reference does not change the speed of light.
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.
If zero mass particle have a speed c in one reference frame Can they be found at rest in other frame?
"c" is usually used, in this context, for the speed of light. If such a particle has the speed of light in one frame of reference, then, strange as it may seem, it will have the speed of light in ANY frame of reference.
How can you say that rest and motion are relative terms?
a body is said to be at rest if it does not change its position relative to a reference frame similarly a body is said to be in motion if it changes its position relative to any reference frame.
Difference between inertial frame of reference and non-inertial frame of reference?
An inertial frame of reference (FOR) is a non-accelerating FOR , for example if a person is observing a moving car while at rest or while moving at constant velocity, he is in an inertial FOR. A non-inertial frame of reference is an accelerating FOR for example a rotating FOR. ( Rotation requires centripetal force and centripetal acceleration so any rotating object always requires a centripetal acceleration to rotate.)
Is absolute motion possible?
Absolute motion is motion relative to a presumed absolute reference frame. Special Relativity posits that the laws of nature are perfectly symmetrical with respect to any inertial reference frame. This implies that there is no absolute reference frame, and that absolute motion is a useless concept.
Where is the fixed point in the universe?
There do not appear to be ANY "fixed points" in the Universe. Everything is in motion, and there is no "preferred" frame of reference.

Frame of reference?
Frame of Reference :A set of axes, taken as being for practical purposes at rest, that enables the position of a point or body in space to be defined at any instant of time.Reference Point : A point with respect to which other points, lines etc. are referred, usually in terms of distance or direction, or both.
How many terrestrial years are experienced by the crew of a ship travelling at the speed of light across one light year?
Not possible for objects with mass to travel at the speed of light.However the time dilation equation of special relativity indicates that objects that can travel at the speed of light (massless particles like the photon), they would experience no passage of time at all. In other words, they arrive at their destination (in their frame of reference) at the same time as they departed from their point of origin (in their frame of reference). Of course it does not look like that to us (in our frame of reference) where we will see the photons take a year to make the trip.
Can you explain a independent variable?
Independent variables do not depend on any other. Like when you count something with time, the time is independent. If you measure the elevation of a road with distance, the distance is independent.
