The average density of a basketball ranges from 0.70/g/cm3 – 0.80g/cm3. … By comparison, a bowling ball’s average density ranges between 1.32-1.36g/cm3. To find the density of a basketball you divide its mass by its volume. Example: Basketball Density = 0.625kg/434 cubic inches.
Do basketballs float?
Whether or not an object has buoyancy depends mostly on two factors: the amount of water an object displaces and the density of an object. … However, a basketball is not very dense and displaces more water; therefore, it floats.
Why does a rock have more density than a tennis ball?
The tennis ball is larger than the rock or marble, rocks and marbles are solid. Tennis balls are hollow and filled with air. The air inside the tennis ball weighs less than the inside of a rock or marble, so the tennis ball floats.
How far will an object sink in water?
Specifically, when placed in water, an object sinks into the water until it displaces an amount of water equal to its own mass. The more mass an object has, the further it sinks. A 1 g object will sink until it displaces 1 g of water. A 2 g object will sink until it displaces 2 g of water.

Why Ships don’t sink but a pin does?
A ship floats on water but the needle sink because of the Buoyancy. Archimedes’s law states that a body immersed in water displaces its volume of water, and if this displaced volume of water weighs more than the body immersed, the body will float.
Why are things lighter underwater?
A: When objects are placed in water, their mass does not change. … Archemedes’s principle states that the force pushing on an object under water, is equal to the mass of the water it has pushed out of the way. So things apear lighter because the water is actually helping to push it up.
When we drop an iron ball in mercury it will?
The ball will float. It is because the density of the iron ball is lesser than the density of mercury.
