If an object weighs more than the weight of the water it displaces, it will sink. On the other hand, if the object weighs less, then it will float. Now, back to your question.. I think it will be easier to swim in the sea because of two reasons.. [spoiler]For sure, effort is there.[/spoiler] 1st, the saltwater somehow contributes on the weight of our body in the water. if ur body will float, then it will be easier for you to learn swimming. 2nd w/c was based on my experience, [spoiler]ambiance matters. hahah, who will not dare to learn swimming if the atmosphere is ?[/spoiler] okei, now. my turn. question..
