This force diagram shows examples of fluid resistance working against the force the swimmers is applying to swim the stroke of freestyle. The amount of force the swimmer is applying is greater because the swimmer is able to move through the water. Because the forces are unbalanced, the swimmer is able to accelerate. The first law of motion can be found in the stroke of freestyle when the swimmer is able to start and continue doing the stroke unless they stop. The second law is in freestyle because the swimmer has to pull with the amount of force that their body mass requires. The third law is in freestyle because the water pushes back with the same amount of force that the swimmer pulls with.
This force diagram represents the force of fluid resistance against the swimmer and the force that the swimmer is exerting to push off the wall. The force of the swimmer's push is greater than the fluid resistance, which is why the swimmer is able to push off the wall. The first law of motion is in a flip-turn when the swimmer's motion coming from the stroke is continued into the somersault and then carried through the rest of the turn. The second law applies to a flip-turn because the swimmer has to use force to turn into a somersault according to their mass. The third law can be found when the wall pushes back with the same amount of force the swimmer applies.
Within this force diagram, fluid resistance is working against the force of the swimmer's push off the block. The forces are unbalanced because the swimmer is able to break through the water and continue swimming. The first law is applied when the swimmer stays in motion after they push off the block. The second law is shown when gravity along with the swimmer's applied force acts on the mass, and they accelerate. The third law can be found when the block pushes back with the same amount of force the swimmer applies.

Within the start, the swimmer is able to overcome the air resistance and gravity using their push off the block. The forces of air resistance and the swimmer's force are unbalanced since the swimmer is able to dive into the air. The first law of motion can be found within the water when the water stays at rest until the swimmer hits it. The second law can be seen when the amount of mass the swimmer has affects the acceleration into the water. When the swimmer pushes off the block, the block pushes back with the same amount of force. This is Newton's third law of motion.
