The potential energy of the ball was converted to elastic energy. You can think of it as the mass of the ball being mounted to a spring that compresses when you hit the floor - but there will be some friction (both inside the ball, and particularly between the ball and the floor) which will dissipate energy:
it should be hittin the floor
inital velocity (u) should be less
Answer:
Triclinic crystal forms. Also known as the rhombohedron system, its shape is three dimensional like a cube, but it has been skewed or inclined to one side making it oblique. All crystal faces are parallel to each other. A rhombohedral crystal has six faces, 12 edges, and 8 vertices.
