A book sitting on a desk is at rest. It is in motion if the book falls to the floor from the desk.
The "pen at rest or in motion" is a part of a physics lesson used to teach Newton's Laws of Motion. It's used as an example for force, motion, and energy. A pen is in motion during active writing. Otherwise, the pen is at rest when not being used.
Examine the condition when two forces And
The book is experiencing inertia; a state which resists change in motion. This is represented by Newton's first law of motion which states that an object at rest will remain at rest and an object in motion will remain in motion unless acted upon by an external force. Therefore the book in the car continues to move forward until it is acting on by an external force such as the applied force of something in the book's path of motion.
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 ?
example of rest and motion?
yes
In reality, all motion is relative. Whether an object is at rest or in motion depends on the reference frame from which it is observed. Also, you did not indicate any information about the context, so we cannot provide any answer beyond what is given above.
An object at rest tends to remain at rest - an object in motion tends to remain in motion.

A falling book exhibits a change from potential energy (rest) to kinetic energy (motion).
