Newton's Laws of Motion: Three fundamental laws describing the relationship between the motion of an object and the forces acting upon it.
Inertia: The property of an object to resist changes in its state of motion; directly related to mass.
Conservation of Momentum: The total momentum of an isolated system remains constant if no external forces act upon it.
Work-Energy Theorem: The work done on an object equals the change in its kinetic energy.
Rigid Body Dynamics: The study of the motion of solid bodies where deformation is negligible, focusing on translation and rotation.
