Can a small object have more density than a large object?
Yes. The mass per unit volume defines the (mass) density. Size doesn't change the calculated density.
How do you predict the density of a floating object?
By its size
Will every object with the same dimensions have the same density?
No. Density is independent of size.
What happens when a machine changes the size of the force?
The object through which the force is exerted must also change.
What influence will the size of the surface and the mass of a floating object have on the floating ability of the object?
The density is important; for floating an object must have a density under the water density (1 g/cm3).
What is Density how is Calculated How does density change?
density is how dense an object is (see dense) it is calculated by dividing the mass by volume of an object. density can be changed by changing the size or shape or the object
Can a small object have more density than a large object?
Yes. The mass per unit volume defines the (mass) density. Size doesn't change the calculated density.
Does the size of an object change an object's density and why?
No. To calculate density you divide mass by volume (d = m/V) If you double the size of something (volume), then you are doubling the amount of it (mass). The whole reason for using density to compare things is because it is a property of the substance that does not change, regardless of quantity.
Explain why density is a size independent property how does it differ from a size dependent property?
Size independent property is physical properties that do not change when an object changes. Size dependent is physical properties that change when the size of an object changes.
Object A is half the size of B The density of A when compared to B is?
size does not relate to density
How do you predict the density of a floating object?

Will every object with the same dimensions have the same density?
No. Density is independent of size.
What happens when a machine changes the size of a force?
The object through which the force is exerted must also change.
What happens when a machine changes the size of the force?
The object through which the force is exerted must also change.
Does density depend on the size of an object?
No. If an object is homogeneous, then you can cut it up into a bazillion smaller pieces, and every piece has the same density as the original object had.
What influence will the size of the surface and the mass of a floating object have on the floating ability of the object?
The density is important; for floating an object must have a density under the water density (1 g/cm3).
How heavy is an object relative to its size the ratio of mass to volume?
The mass of an object is equal to the object's density multiplied by the volume (size) mass (kg) = density (kg/m3) x volume (m3)
