Rigid body physics is a fundamental concept in computer graphics, game development, and robotics. It describes the motion and interaction of solid objects that are assumed to be infinitely rigid, meaning they do not deform or change shape under the influence of forces. In simulations, these objects are typically represented by their position, orientation, linear velocity, and angular velocity. The motion of a rigid body is governed by Newton's laws of motion, specifically Newton's second law, which relates the net force and torque acting on the body to its linear and angular acceleration.

Simulating rigid body dynamics involves calculating these accelerations based on applied forces (like gravity, user input, or collisions) and then integrating these accelerations over time to update the body's velocity and position. Collision detection and response are crucial aspects of rigid body simulations. When two or more rigid bodies collide, the simulation must accurately determine the impact and calculate the resulting changes in their velocities and trajectories. This often involves complex mathematical formulations to ensure realistic interactions, such as the conservation of momentum and energy.

Rigid body physics engines are widely used to create immersive and interactive virtual environments. They enable realistic behaviors for objects, making games more engaging and simulations more accurate. The complexity of these simulations can vary greatly, from simple stacking of blocks to intricate machinery with multiple interacting parts. Efficient algorithms and optimizations are often employed to handle a large number of rigid bodies in real-time simulations.
