"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 the motion of objects under the influence of force, including objects at rest.
Kinematics: The branch of mechanics that describes the motion of objects without considering the forces that cause the motion.
Dynamics: The branch of mechanics that describes the motion of objects in relation to the forces acting upon them.
Newton's Laws of Motion: Three laws that describe the relationship between an object's motion and the forces acting upon it, including the law of inertia, the relationship between force, mass, and acceleration, and the law of action and reaction.
Work: The amount of energy transferred by a force through a distance.
Energy: The ability of an object to do work.
Potential Energy: The energy that an object possesses due to its position in a gravitational field or due to its configuration.
Kinetic Energy: The energy that an object possesses due to its motion.
Conservation of Energy: The principle that the total energy of a closed system remains constant over time and cannot be created or destroyed.
Momentum: The product of an object's mass and velocity, measuring the amount of motion that it possesses.
Conservation of Momentum: The principle that the total momentum of a closed system remains constant over time and cannot be created or destroyed.
Collisions: The interactions between two or more objects that result in a change in their momentum.
Circular Motion: The motion of an object along a circular path.
Centripetal Force: The force that is directed toward the center of a circular path and causes an object to move along that path.
Rotational Motion: The motion of an object around an axis of rotation.
Torque: The force that is applied to an object to cause a rotational motion.
"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."
