Question

Between size,shape,weight and material which one does not affect floating and sinking?

Answer 1

The factor that does not directly affect whether an object will float or sink is **shape**. While shape can influence the way an object interacts with water (in terms of drag and stability), it is the density (mass per unit volume) of the object relative to the density of the fluid that primarily determines whether it will float or sink. Size, weight, and material contribute to the overall density of an object—therefore influencing its buoyancy—while shape alone does not determine buoyancy.
