It's mostly a swimmer's arms and hands, but of course, kicking is a part too. Those two things combined make up the most of the movement.

A person who moves through water could be a swimmer, a SCUBA diver, a surfer, a water skier, or maybe Aquaman.
In the fingers of a swimmer, water generally flows from the fingertips towards the wrist. As the swimmer propels themselves through the water, the movement creates a forward motion, causing the water to be pushed back and around the fingers. This flow can vary slightly based on the swimmer's technique, but the predominant direction is from the fingertips inwards towards the hand and arm.
The answer is: The swimmer exerts a reaction force on the water.
they cup their hands so that no water go through you hand making the force increased
This term means that you are a good swimmer, fish can stride through the water and therfore the swimmer is good.
I'd say it's called a "swimmer" or a fish.
An example of fluid friction is when a swimmer experiences resistance as they move through water. The water molecules come in contact with the swimmer's body, causing a drag force that makes it harder for them to move forward smoothly. This frictional force acts in the opposite direction to the swimmer's motion.
A backstroker is a swimmer who swims backstroke.
Swimmers experience forces such as drag, buoyancy, and propulsion. Drag is the resistance of water against the swimmer's movement, while buoyancy helps to keep the swimmer afloat. Propulsion is the force generated by the swimmer's movements to propel themselves through the water.
The third law of motion, formulated by Sir Isaac Newton, states that for every action, there is an equal and opposite reaction. In swimming, this principle is observed when a swimmer pushes against the water with their hands and feet; the water pushes back with an equal force, propelling the swimmer forward. This interaction between the swimmer and the water is crucial for effective propulsion and movement through the water.
