# 3D Physics

These pages aim to give enough physics information to allow physical objects to be simulated by a computer program.

 Overview Overview of methods to simulate physics using analytical and numerical methods Statics Situation where forces are in balance. Kinematics Kinematics: The study and description of motion, without regard to its causes, including position, orientation, velocity, angular velocity, acceleration. For example, we can calculate the end point of a robot arm from the angles of all its joints. Alternatively, given the end point of the robot arm, we could calculate the angles and settings of all its joints required to put it there (inverse kinematics - IK). Dynamics Covers the causes of motion in terms of properties like mass and inertia. Including movement in free space, rotation of solid body, Inertia, Energy and Momentum, Collision, Impulse and Spring, mass, damper model Numerical methods In some cases, especially when we are not dealing with solid bodies we may need to use other methods such as Finite Element Method, relaxation methods or equations model Particles and Fluids Water or Gas and particles Table Top Physics Gives examples and thought experiments to illustrate some of the problems and complexities that we need to solve Other Other physics topics that might be involved such as Light, Sound, Heat, Electricity/Magnetism and Human Animation Algorithm to animate solid object in computer program This puts together the kinematics and dynamics concepts into practical algorithms that can be used in computer programs Quantum Mechanics Physics Books Further reading
