Forces Acting on a Submarine Underwater

When a submarine is moving uniformly underwater, several forces act on it to compensate for each other. These forces include:

a. Thrust Force: The thrust force generated by the submarine's engine propels it forward. This force is responsible for the submarine's motion through the water.

b. Gravity Force: The force of gravity acts on the submarine, pulling it downward towards the center of the Earth. This force is responsible for the submarine's weight.

c. Reaction Force: The reaction force is the force exerted by the water on the submarine in the opposite direction of its motion. According to Newton's third law of motion, for every action, there is an equal and opposite reaction. As the submarine moves forward, it pushes the water backward, and the water exerts a reaction force on the submarine.

d. Buoyant Force (Archimedes' Principle): The buoyant force is the upward force exerted by a fluid on an object immersed in it. It is equal to the weight of the fluid displaced by the object. In the case of a submarine, the buoyant force is exerted by the water on the submerged part of the submarine. This force counteracts the force of gravity and helps keep the submarine afloat.

These forces work together to maintain the submarine's equilibrium and allow it to move smoothly underwater. The thrust force propels the submarine forward, while the reaction force and buoyant force counteract the forces of gravity and provide stability.

Please note that the above information is based on general knowledge about submarines and the forces acting on them. For more specific and detailed information, it is recommended to refer to reliable sources on naval engineering or submarine technology.
