Why the ball has definite shape?

Answer 1

A ball has a definite shape due to its symmetrical design and uniform distribution of mass, which allows it to maintain a consistent curvature. This shape is typically spherical, enabling it to roll smoothly in any direction. The materials used in its construction, such as rubber or plastic, are also engineered to retain this shape under pressure and during use. Overall, the combination of design, material properties, and manufacturing processes ensures that the ball maintains its defined form.
