Force is a push or pull acting upon an object as a result of its interaction with another object. It can change the state of motion or shape of a body.

Forces are classified as contact forces (like friction and muscular force) and non-contact forces (like gravitational and magnetic forces).

Newton’s three laws describe the relationship between a body and the forces acting on it: Law of Inertia, Law of Acceleration (F = ma), and Law of Action-Reaction.

Forces are used in walking, driving, lifting objects, pressing brakes, opening doors, and in various mechanical and industrial processes.

Force is a fundamental concept that helps explain motion, equilibrium, and various physical phenomena — forming the basis of mechanics.
