In physics, a force exerted on an object by a person or another object is categorized by this designation. It represents the interaction between the external agent and the object, resulting in a push or pull. For example, a person pushing a box across the floor or a rope pulling a sled demonstrates this type of force in action. Its magnitude and direction directly influence the object’s motion, causing acceleration or deceleration.
Understanding this concept is crucial to analyzing the dynamics of physical systems. It is a foundational element in Newtonian mechanics, allowing for the prediction of an object’s behavior under different scenarios. Its application extends to various fields, from engineering, where it informs the design of structures and machines, to sports, where it explains the motion of balls and athletes.
