Answer:
The buoyant force is the primary reason why there is little resistance between a canoe and the surface of the water on a calm day. Buoyant force is an upward force that acts on any object submerged in a fluid. It arises due to the pressure difference between the bottom and the top of the submerged object. The pressure at the bottom of the object is greater than the pressure at the top, resulting in a net upward force that counteracts the weight of the object. This upward buoyant force allows the canoe to float easily on the water's surface, experiencing minimal resistance.
