"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."
Study of motion and forces.
Kinematics: Describes the motion of objects without considering the forces acting on them. It includes the concepts of position, velocity, acceleration, and time.
Dynamics: Deals with the forces that cause motion of objects. It includes the concept of force, mass, and acceleration.
Newton's Laws of Motion: Describes how forces interact with objects and how objects react to these forces.
Work, Energy, and Power: Deals with the relationship between the work done on an object, the energy that an object possesses, and the rate at which work is done.
Linear Momentum: Deals with the motion of objects and the amount of motion that they possess due to their mass and velocity.
Circular Motion: Deals with the motion of objects that travel in a circular path.
Gravity: Describes the force that attracts objects to one another.
Friction: Deals with the force that opposes the motion of objects.
Oscillations and Resonance: Describes the motion of systems that go back and forth around a point of equilibrium.
Fluid Mechanics: Deals with the behavior of fluids, such as liquids and gases.
"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."
