Earth.
An origin or zero point.
The most common frame of reference is the observer himself and, by extension, the room, lab, neighborhood, or environment in which he feels himself to be at rest.
A tree can be used for a frame of reference for the motion of a snowboarder.
Earth is the most common frame of reference.
That's right, motion cannot be measured unless you have some frame of reference within which to measure it.
Frame Of Reference. which means a framework that is used for the observation and mathematical description
An origin or zero point.
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

the inertial reference frame is not absolute. because motion is not absolute. motion is relative depends on who's looking/observing.
Motion is relative to an observer's frame of Reference.
Relative motion is movement in relation to a frame of reference.
According to the current understanding of physics, there is no such thing as "absolute motion". There is nothing in space that distinguishes one frame of reference from another. There is no "preferred" reference frame. Thus, if you don't specify a frame of reference, you don't know how an object is moving. Unless, of course, the frame of reference is implicit; in some practical situations it is.
Earth is the most common frame of reference.
usually the motion of your frame of reference is 0. When you are in a train going 50 mph, your frame of reference would be you are going 0 mph and the tracks are traveling at -50 mph.
