-A physics engine is software that mimics the laws of our physical world. It gives virtual objects [Force](/wiki/force) and momentum, calculating their movement and [Collision](/wiki/collision) with other elements. This creates believable interactions, from tumbling blocks to flowing water, vital for [Video Game](/wiki/video_game) and [Simulation](/wiki/simulation) fidelity.
-At its core, physics engines utilize [Kinematics](/wiki/kinematics) to describe the motion of objects without considering the forces causing that motion. This involves calculating position, velocity, and acceleration. More advanced applications use [Inverse Kinematics](/wiki/inverse_kinematics), where the desired end position of a body part (like a character's hand) is specified, and the engine calculates the required joint rotations to achieve it, simplifying [Animation](/wiki/animation).
-Another crucial aspect is [Constraint Solving](/wiki/constraint_solving). Constraints are rules that limit the movement or relationship between objects, such as keeping two objects attached by a joint, preventing penetration, or defining a specific range of motion. The engine continuously solves these constraints to maintain physical realism and prevent objects from behaving unnaturally.
-While [Kinematics](/wiki/kinematics) provides the fundamental description of motion, and [Inverse Kinematics](/wiki/inverse_kinematics) aids in controlling complex articulated bodies for [Animation](/wiki/animation), [Constraint Solving](/wiki/constraint_solving) acts as the enforcement mechanism. It ensures that the calculated movements and poses — whether derived from forces or specific kinematic goals — consistently adhere to the defined physical rules and interactions, preventing unrealistic outcomes and making the simulated world believable.
