Why a human can swim in the water ?
Dear Student,
Human body is slightly less dense than water. The weight of a body in water largely cancels due to the buoyancy force. While swimming we move our body through water. Water being more dense and viscous than air we cannot walk through it as we do so in air. It is this viscous drag of water which let us to move forward while doing work through various swimming actions.
Regards
