Question

As Newton's third law says, we can stand on ground because we apply a force on ground because of our weight, and the ground resists. We cannot stand on water because water cannot resist the force applied by our weight. But we can swim on water because we push the water backwards, and water resists and pushes us forward. How can water resist us while swimming but not while standing on the water surface?

Answer 1

Well when we are swimming the reason we move is the result of the reaction force that happens when we applay an action.

That is when we try to swim we appaly a force on the water with our hands as result a reactive force is created on us by water
which makes us move forward. The resistance offred by water in this case is very little.

So if you ask me does water offer resistance i would say yes but in a small amount and it only has power in the horizontal (swimming) direction

Thats all
