ClassicalForce is a term used to describe the set of forces considered in classical (Newtonian) mechanics. In this framework, forces are vector quantities that cause changes in the motion of bodies, described by Newton's laws.

Common components include contact forces such as friction, normal reaction, and tension, as well as push or pull forces. Field forces treated in a Newtonian sense include gravity and, in some contexts, electrostatic and magnetic interactions. The net force acting on a system is the vector sum of these contributions.

The motion of a particle of mass m under a net force F is governed by F = ma, where a is acceleration. For extended bodies, rotational dynamics introduce torque and angular acceleration, with constraint forces arising from connections or surfaces. In non-inertial reference frames, fictitious forces may appear, though the underlying physics remains the same and can be translated to an inertial frame for analysis.

Historically, ClassicalForce concepts were developed and refined in the 17th and 18th centuries, with Isaac Newton's Principia laying the foundation and later contributions from Lagrange, Hamilton, and others expanding the formalism. They underpin most everyday engineering, biomechanics, and physics education, providing intuitive and practical tools for analyzing motion.

In contemporary physics, classical forces remain effective models at speeds and scales where relativistic and quantum effects are negligible. They continue to guide design, simulation, and problem-solving across engineering, mechanics, and applied sciences, while offering clear connections to fundamental principles.
