"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 forces that cause motion and how they interrelate.
Kinematics: The study of motion without considering the forces that cause that motion. It involves concepts such as displacement, velocity, acceleration, and time.
Dynamics: The study of how forces affect the motion of objects. It involves concepts such as force, mass, acceleration, and momentum.
Newton's Laws of Motion: Three fundamental laws that describe the relationship between forces and motion. They are used to predict the motion of objects and are essential in understanding dynamics.
Friction: The force that opposes motion between two surfaces that are in contact. It is a major factor in many dynamics problems.
Work and Energy: The study of the relationship between the work done on an object and the change in the object's energy. It is used to predict the motion of objects and is essential in understanding dynamics.
Momentum: The product of an object's mass and velocity. It is a measure of the object's motion and is conserved in collisions and other interactions.
Circular Motion: The motion of an object along a curved path. It involves concepts such as centripetal force, tangential velocity, and radial acceleration.
Gravity: The force that attracts two objects with mass towards each other. It is a fundamental force in the universe and is responsible for the motion of planets, stars, and galaxies.
"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."
