Newton's laws of motion are the fundamental principles of classical mechanics that describe the relationship between a body and the forces acting upon it. They form the basis for much of modern physics, from simple motion to the behavior of fluids and solids.

The three key concepts in Newton's laws of motion are:

  • Inertia: An object at rest will remain at rest, and an object in motion will remain in motion at a constant velocity, unless acted upon by a net external force.
  • Force: The rate at which momentum changes is equal to the force applied, and force is always accompanied by an equal and opposite reaction force.
  • Acceleration: The acceleration of an object is proportional to the net force acting on it and inversely proportional to its mass.

These three concepts are the foundation for understanding how objects move and how forces affect their motion. By applying these principles, physicists and engineers can predict the behavior of complex systems, from airplanes and satellites to subatomic particles.
