Yes, a paddle can be considered a type of lever. In this case, the paddle acts as a lever arm, with the pivot point being where it enters the water. When force is applied to one end of the paddle, it generates a mechanical advantage that allows for efficient movement through the water. This lever action helps propel a boat or kayak forward.

James Joule investigated his theories by conducting experiments to study the relationship between heat, work, and energy. He made significant contributions to the development of the first law of thermodynamics through his work on the mechanical equivalent of heat. Joule's famous experiment involved using a paddle wheel in a container of water to show the conversion of mechanical energy into heat.

B/c human knew oars and paddles, and that they could be used to power a boat through water. So before the invention of the propeller, paddle wheels were used as a sort of mechanical oarsmen.
you paddle with it on a canoe!!
Yes, a handheld boat paddle is a 3rd class lever because the effort (force applied by the user) is between the load (water resistance) and the fulcrum (pivot point where the hand holds the paddle). In this arrangement, the user applies force at a mechanical disadvantage, but gains increased speed and range of motion for paddling.
