How does Newton's second law apply to swimming?
The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
what we can say is that due to the external force applied we can have acceleration. In the case of swimming we apply backward force on the water which in turn applies a frontward force to us. So we are able to swim. This seems like the condition for Newton's third law of motion but actually it is a generalized case of the second law as the term force and acceleration(movement) is being considered.
Thus, In this way Newton's second law apply to swimming?
