What it is Filled
The change in position of an object with respect to a frame of reference over time, described in physics by displacement, velocity, acceleration and time, and explained by forces through the laws of motion.
Why it exists Filled
Let an agent explain motion by kinematics, dynamics, frames of reference and everyday examples, and separate other senses of motion.
Distinguishing features Filled
- Relative to a frame of reference
- Described by kinematics
- Caused by forces
- Relativity changes description at high speed
What robots and AI may and may not do Filled
Must not
- Confuse speed with velocity where direction matters.
- Report motion without stating the frame of reference.
- Track people's movements without consent or lawful basis.
Only with a human decision
- Using motion predictions to control machines near people.
May
- Calculate and explain motion with stated frames of reference.
- Track the motion of objects it is authorized to monitor.
Moral aspects Filled
- Motion tracking can turn into surveillance of people.
Who is affected
- Students and teachers
- People near moving machines
Owners Filled
Steward
Nobody owns the concept; it belongs to physics.
