Answer 1

Answer:

The principle of the conservation of momentum dictates that as the stone enters the water and pushes some of the water downwards, the stone is forced upwards. ... If its velocity is less than this value, the stone skims across the water for a short distance and then sinks.••••••••

Answer 2

Answer:

Every action has an equal and opposite reaction. When the stone exerts a force on the surface of the water, the water exerts a force back, which makes the stone skip over the top of the water. This is due to the surface tension of water, which makes it behave like a surface. Now if you throw a stone at this surface, at a suitably low angle, it will simply bounce off instead of penetrating. e.g. when you throw a ball at a window, if you throw it almost parallel to the surface, it has a much less chance of breaking through.
