The main forces involved in swimming are the gravitational force, thrust force, and drag force.
The gravitational force of the swimmer, commonly referred to as W=mg, is canceled out by the buoyancy force exhibited by the water on the swimmer.
This leaves the 2 main forces dictating the stroke and speed of the swimmer are thrust force and drag force.
