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.
The object that serves as the reference point for determining motion is known as the frame of reference. It is used to describe the motion of an object relative to another object or observer. The choice of frame of reference can affect how motion is described and analyzed.
According to the Theories of Relativity, time is NOT independent of the reference frame.
The frame of reference for a sunset can be Earth's surface or a stationary observer. In this frame, the sun appears to move below the horizon due to Earth's rotation, creating the perception of a sunset.
Work is force X distance travelled. Force is mass x acceleration. Aceeleration depends on the frame of reference from which one is measuring it. Hence work done depend on the frame of reference from which one is measuring it. QED
You would add the characteristics of the original reference frame itself. For example, if you know the walking speed of a man on a bus with respect to the bus and you want to know the velocity of the man with respect to the ground, find the vector sum of the man's velocity w.r.t. the bus and the bus' velocity w.r.t. the ground. If one reference frame is not a subset of the other, solve first for a reference frame they have in common. For example, if you want to know the velocity of the man in the first example with respect to a passing truck, find his velocity with respect to the ground first. Keep in mind that "forward" can mean different directions in different reference frames.
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.

Frame of reference can be used to describe acceleration.
No, an inertial reference frame is not an absolute reference frame. It is a frame of reference in which an object either remains at rest or moves with constant velocity in a straight line, but it is not considered absolute as its motion can be affected by external forces.
Relative motion is movement in relation to a frame of reference.
A tree can be used for a frame of reference for the motion of a snowboarder.
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.
According to the Theories of Relativity, time is NOT independent of the reference frame.
The property that is absolute and independent of frame of reference is the speed of light.
There is no difference. For Example, reference point means where you see something out of somewhere, and frame of reference means seeing something out of somethings "eyes" i know it sounds weird but i hope i helped.

The phrase usually used for this is "reference frame".
