Why is the state of a physical system completely determined by only positions and velocities, rather than (possibly) other derivatives?
Positions and velocities are fundamental quantities in physics because they describe the location and movement of objects in space and time. They are essential for understanding the behavior of particles and systems, and can be used to predict future positions and velocities based on known laws and equations.
Yes, other quantities such as acceleration, momentum, and energy are also important in physics. However, these quantities can often be derived from positions and velocities, making them more fundamental.
Positions and velocities are complementary quantities. While positions tell us where an object is located, velocities tell us how fast and in what direction it is moving. Together, they provide a complete description of an object's motion.
In classical mechanics, positions and velocities are usually sufficient to describe a system. However, in more complex systems involving quantum mechanics or relativity, other quantities such as spin or spacetime curvature may also be necessary.
Positions and velocities are essential for a wide range of practical applications, including navigation, robotics, and transportation. They allow us to accurately track the movement of objects and predict their future positions, which is crucial for many technological advancements.
