That means, compared to what are you calculating the movement. This might be the Earth, or some other object.
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

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.
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.
