Propeller Thruster
★Exhibit Content: Conservation of Momentum, Reaction Force ★Interaction: Mechanical Interaction ★Operation: Visitors turn the handwheel to rotate the propeller and observe the water flow direction in the pipe above the water tank. ★Exhibit Description: The exhibit consists of a transparent water tank, propeller, handwheel transmission mechanism, and pipes. Visitors turn the handwheel to drive the propeller, accelerating the water flow, visually demonstrating the working principle of a propeller thruster generating reaction force by changing the momentum of water. ★Scientific Principle: According to the law of conservation of momentum, the propeller accelerates the water flow, increasing the momentum of the water, thereby generating a reaction force of equal magnitude and opposite direction, propelling the ship forward. Momentum is the product of mass and velocity; different mass and velocity changes produce different degrees of momentum change. This exhibit visually presents this principle through the change in water flow direction. A propeller thruster accelerates the water passing through it, causing an increase in the momentum of the accelerated water, generating a reaction force that propels the ship. Since momentum is the product of mass and velocity, different masses combined with different velocity changes can cause different degrees of momentum change.
