Which force would be involved when a boat moves forward by the engine?

Explanation:
Forward motion from the engine comes from thrust. When the propeller spins, it pushes water backward; in response, the water pushes the boat forward. That forward push is the thrust, the force that actually drives the boat ahead. Gravity pulls the boat downward, and buoyancy pushes it upward, helping it float. Friction with the water (drag) resists motion, so the engine must produce enough thrust to overcome that resistance. But the force that moves the boat forward is thrust.
