Simulation of Physics is one of the most important functionalities of modern game engines. Explain how Unity game engine provides simulation of rigidbody movements. Answering this question you should consider relevant theoretical concepts, Unity components and API in relation to: - Linear motion with constant velocity and with acceleration - Force, linear momentum, impulse - Rotation, torque, moment of inertia, angular momentum - Projectiles - Elastic and inelastic collisions - Friction You can use sketches, mathematical equations, diagrams and API function calls to explain concepts and processes.
