"Classical mechanics is a physical theory describing the motion of macroscopic objects, from projectiles to parts of machinery and astronomical objects, such as spacecraft, planets, stars, and galaxies."
Classical mechanics provides a framework for understanding the motion of macroscopic objects and is used in computational physics to study the behavior of fluids and other complex systems.
Kinematics: The study of motion in terms of displacement, velocity, and acceleration.
Dynamics: The study of the causes of motion, including force, mass, and acceleration.
Newton's laws of motion: A set of three laws that describe the relationship between an object's motion and the forces acting on it.
Work and energy: The study of the relationship between work done on an object and its change in energy.
Conservation of energy: The principle that the total amount of energy in a system is constant, although it can be transformed from one form to another.
Potential energy: The energy stored in an object due to its position or configuration in a force field.
Kinetic energy: The energy of motion possessed by an object.
Momentum and impulse: The study of the relationship between an object's mass, velocity, and momentum, and the effects of a force acting on it over a period of time.
Conservation of momentum: The principle that in the absence of external forces, the total momentum of a system of objects is constant.
Circular motion: The study of objects moving along circular paths, including the centripetal force required to maintain circular motion.
Oscillations: The study of the motion of objects that repeatedly move back and forth around an equilibrium position, including simple harmonic motion.
Waves: The study of the properties of waves, including their propagation, reflection, refraction, and interference.
Fluid mechanics: The study of the properties and motion of fluids.
Gravitation: The study of the force of gravity and its effects on objects in space.
Thermodynamics: The study of the relationship between heat, energy, and work.
Statistical mechanics: The study of the behavior of large systems of particles, based on statistical probabilities.
Special relativity: The study of the effects of high-speed motion and the properties of space and time in the absence of gravity.
Quantum mechanics: The study of the behavior of subatomic particles and the properties of matter and energy at the quantum level.
Computational methods: The use of algorithms and computer simulations to solve complex problems in classical mechanics.
Kinematics: This branch of classical mechanics deals with the study of motion without taking into consideration the forces that cause the motion.
Dynamics: This branch deals with the study of motion with respect to the forces that cause the motion.
Statics: This deals with static equilibrium or the study of the forces acting on a system in a state of rest.
Celestial mechanics: This involves the study of the motion of celestial objects like planets, moons, and comets under the influence of gravity.
Continuum mechanics: This deals with the study of the mechanical behavior of materials modeled as continuous matter.
Lagrangian mechanics: This is a mathematical approach to studying the motion of systems that takes the path of least action.
Hamiltonian mechanics: This is also a mathematical approach to studying the motion of systems that uses a set of equations called Hamilton's equations.
Rigid body dynamics: This is the study of the motion of solid objects that maintain their shape under the influence of external forces.
Fluid mechanics: This branch of classical mechanics deals with the study of the motion of fluids, both gases and liquids.
Elasticity: This branch of mechanics deals with the study of the mechanical behavior of solid materials that can deform and return to their original shape.
Acoustics: This is the study of sound, including its production, transmission, and reception.
Thermodynamics: This deals with the study of the relationship between heat, energy, and work.
Statistical mechanics: This involves the application of statistics and probability theory to classical mechanics to understand the behavior of complex systems.
Analytical mechanics: This is a branch of classical mechanics that uses advanced mathematical techniques to solve complex problems in mechanics.
"For objects governed by classical mechanics, if the present state is known, it is possible to predict how it will move in the future (determinism)."
"For objects governed by classical mechanics, if the present state is known, it is possible to [...] how it has moved in the past (reversibility)."
"The 'classical' in 'classical mechanics' does not refer classical antiquity, as it might in, say, classical architecture. On the contrary, the development of classical mechanics involved substantial change in the methods and philosophy of physics."
"The qualifier distinguishes classical mechanics from physics developed after the revolutions of the early 20th century, which revealed limitations of classical mechanics."
"It consists of the physical concepts based on foundational works of Sir Isaac Newton, and the mathematical methods invented by Gottfried Wilhelm Leibniz, Joseph-Louis Lagrange, Leonhard Euler, and other contemporaries in the 17th century to describe the motion of bodies under the influence of forces."
"Later, more abstract methods were developed, leading to the reformulations of classical mechanics known as Lagrangian mechanics and Hamiltonian mechanics."
"These advances, made predominantly in the 18th and 19th centuries, extend substantially beyond earlier works, particularly through their use of analytical mechanics."
"They are, with some modification, also used in all areas of modern physics."
"Classical mechanics provides accurate results when studying large objects that are not extremely massive and speeds not approaching the speed of light."
"When the objects being examined have about the size of an atom diameter, it becomes necessary to introduce the other major sub-field of mechanics: quantum mechanics."
"To describe velocities that are not small compared to the speed of light, special relativity is needed."
"In cases where objects become extremely massive, general relativity becomes applicable."
"A number of modern sources do include relativistic mechanics in classical physics, which in their view represents classical mechanics in its most developed and accurate form."
"[Classical mechanics describes] the motion of macroscopic objects, from projectiles to parts of machinery and astronomical objects, such as spacecraft, planets, stars, and galaxies."
