```				   if a baloom going up,then it's p.e.....and why?

```

```										As the balloon goes up, there are twoforces acting on it- gravity and the upward force of buoyancy. The buoyant force is obviously greater in magnitude than the gravity. In addition, the ballon moves in the direction of buoyancy. therefore, potential energy decreases.

if the velocity of river is 6i^ m/s and the velocity of boy in still water is (8i^ + 6j^)m/s. then the velocity of boy w.r.t. river water is. should it be same (8i^ + 6j^)m/s?

Yes. Because the swimmer is trying to swim with the same speed as he swims in the still water. It doesn’t matter whether the river is flowing or not, the velocity of the swimmer with...
