Thakshashila (talk | contribs) Created page with "= Force: Definition and Mathematical Representation = == Introduction == '''Force''' is a fundamental concept in physics that describes a push or a pull acting upon an object. It causes objects to accelerate, decelerate, remain in place, or change direction. The concept of force is central to Newtonian mechanics. == Definition == Force is defined mathematically by Newton's Second Law: F = m × a Where: * F is force in newtons (N), * m is mass in kilograms (kg), *..." |
