- When we swim in water, two forces acts on our body. One is the gravitational force equal to our weight in the downward direction and the other is the up thrust or buoyant force in the upward direction. Hence, the net downward force or the apparent weight of our body is less than our actual weight. Therefore, we feel lighter, when we swim.
