since by definition motion is 'The act, process, or state of changing place or position; movement; the passing of a body from one place or position to another, whether voluntary or involuntary; -- opposed to rest', then frame of reference (according to the physics def.) is the coordinates used to measure this motion. also, many people modify frame of reference by using sub categories, such as observational reference frame, which implies that we care about the state of motion more. macroscopic and microscopic frames of reference set themselves apart by focusing on the scale of observations.
A tree can be used for a frame of reference for the motion of a snowboarder.
That's right, motion cannot be measured unless you have some frame of reference within which to measure it.
Frame of reference is related to motion because reference points enable us to see that an object is moving. ======================== Motion is related to a frame of reference because there is no such thing as 'real' motion or 'real' rest. 'Rest' and 'motion' are always with reference to something else. The book that you are reading is at rest with reference to your lap, your lap is at rest with reference to the seat you're sitting in, and you, the book, and the seat are all at rest with reference to the airplane you're flying in at 400 miles per hour. See what I mean ?
Relative motion is movement in relation to a frame of reference.
Only relative to some frame of reference.
Frame Of Reference. which means a framework that is used for the observation and mathematical description

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.
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.

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.
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
