The discussion centers on the concepts of momentum and inertia within the framework of Newtonian physics. It establishes that both momentum and inertia are relative to the chosen reference frame, meaning their values can change based on the observer's perspective. In contrast, certain quantities such as mass, distance, and duration remain invariant regardless of the reference frame. This distinction is crucial for understanding the fundamental principles of classical mechanics and their implications in relativity.
PREREQUISITESStudents of physics, educators teaching classical mechanics, and anyone interested in the foundational concepts of motion and reference frames in both Newtonian and relativistic physics.
Yes.synch said:if the frame of reference is altered so the speed matches, the momentum apparently vanishes (?!).
I don’t understand this comment.synch said:Likewise with apparent inertia during acceleration of an object - similar acceleration of the frame can radically alter the perceived affect.
In Newtonian physics some concepts are relative to the chosen reference frame and other concepts are invariant under a choice of reference frame. Velocity, energy, momentum, etc, all depend on the reference frame. Mass, distance, duration, etc., do not.synch said:Can absolute measurements be made in Newtonian physics?
