Not necessarily. While copper always has the same density (apart from thermal expansion) , a copper ball may be hollow. Modern pennies are not made entirely of copper, but rather have a thin copper coating while the rest of the coin is zinc, which is somewhat less dense.
Penny. Put the ball, duck and penny in water. Only the penny sinks.
An object with a high density, such as a lead ball, can have a small capacity (volume) but a large mass. This is because density is the ratio of an object's mass to its volume, so objects with high density have a lot of mass packed into a small space.
The density of a tennis ball is approximately 0.074 grams per cubic centimeter.
If the density of the ball bearing is less than the density of the given oil, the ball bearing will float in the oil since objects with lower density float on substances with higher density. The buoyant force acting on the ball bearing will be greater than its weight, causing it to rise to the surface of the oil.
A beach ball would not have density, as density is a measure of an object's mass divided by its volume. Both the beach ball and the beach would have different densities due to their composition and materials.

a season ball is made of wood and copper
Yes, a Golf ball does have a Higher density than a pingpong ball. I think because if a fusion is compacted real close, it has a higher density than the object that is seperated .
i think it does not sure
It depends on what you want to float it on. For instance if you want to float a ball in oil the ball's density must be less than the oil's density.
BB's are not all made of the same materials. Some of the best are nearly pure copper. The density of copper is 8,920 kg/m3. Your instructor probably has some BB's and lab equipment he expects you to use to determine their density. Measure a BB and calculate it's volume. Weigh it and and convert your measurements into kg/m3.

If the density of the ball bearing is less than the density of glycerine oil, the ball bearing will float on the surface of the glycerine oil. Objects with lower density than a liquid will float on that liquid due to buoyancy force.
