ship resistance

Ship resistance refers to the forces that oppose a ship's movement through water. It primarily consists of two components: viscous resistance, which arises from the friction of water flowing over the ship's hull, and wave resistance, caused by the energy required to create waves as the ship moves. Other factors include air resistance and the design of the ship itself. Understanding ship resistance is crucial for improving fuel efficiency, optimizing speed, and enhancing the overall performance of vessels, as it directly affects how much energy is needed for the ship to travel.
