Tractive power is the force or ability of a machine to pull, push or move something forward. There are various synonyms which can be used to describe the same, including "tractive force," "pulling power," "towing capacity," "propulsive force," "thrust," "drag," and "tractive effort." In the context of vehicles, the tractive power is the measure of their ability to tow or carry weight. In industrial applications, the tractive power measures the capacity of machines such as cranes or tractors to handle heavy loads. Similarly, in physics, tractive power is associated with the attractive or repulsive forces of magnetism or gravity. Hence, all these synonyms refer to the same thing - the ability of an object or machine to move or pull something towards it.
