Physical object

A physical object is a tangible entity that occupies space and has properties such as mass, shape, and location. Its boundaries and identity can depend on how it is distinguished from its surroundings.

Matter: Matter is physical substance that has mass and occupies space. Objects are commonly understood as bounded portions of matter.
Classical mechanics: Classical mechanics describes the motion of bodies under forces using Newtonian or related laws. It provides a framework for predicting how ordinary objects move and interact.
Physical field: A physical field assigns a physical quantity to each point in space and time. Unlike a bounded object, a field is represented as distributed across regions of space.
Object-oriented programming: Object-oriented programming organizes software around objects that combine data with operations. Its objects are computational models, not necessarily tangible entities.
Mass: Mass is a property that measures an object's inertia and contributes to its gravitational interactions. It is a measurable property often used to characterize physical objects.
Newton's laws of motion: Newton's laws relate an object's motion to inertia, applied forces, and interactions. They connect an object's mass and motion to the forces acting on it.
Physical system: A physical system is a selected set of interacting entities treated as a unit for analysis. A system is defined by an analytical choice and may contain many objects.
Computer vision: Computer vision develops methods for extracting information from images and video. It attempts to identify and locate physical objects in visual data.
Spatial extent: Spatial extent is the size and range of a thing's occupation of space. An object's occupation of space gives it size and spatial boundaries.
Center of mass: The center of mass is the weighted average position of the mass in a system. It lets mechanics model an extended object’s translation as motion of a single point.
